> You might look at the standard KYC questionnaire for a new retail account and think “Really? You ask questions which have obviously correct answers. You give people less than a tweet worth of space to answer them. How could this possibly catch any criminals not stupid enough to write Occupation: Drug Dealer?” […] this is not the only mechanism by which KYC questionnaires have a stochastic effect; they’re also useful in an entirely different part of the crime lifecycle. Many, many crimes involve lies, but most lies told are not crimes and most lies told are not recorded for forever. We did, however, make a special rule for lies told to banks: they’re potentially very serious crimes and they will be recorded with exacting precision, for years, by one of the institutions in society most capable of keeping accurate records and most findable by agents of the state.
> This means that if your crime touches money, and much crime is financially motivated, and you get beyond the threshold of crime which can be done purely offline and in cash, you will at some point attempt to interface with the banking system. And you will lie to the banks, because you need bank accounts, and you could not get accounts if you told the whole truth.
> The government wants you to do this. Their first choice would be you not committing crimes, but contingent on you choosing to break the law, they prefer you also lie to a bank. […]
> Particularly in white collar crime, establishing complicated chains of evidence about e.g. a corporate fraud, and mens rea of the responsible parties, is not straightforward. But then at some point in the caper comes a very simple question: “Were you completely honest with your bank?” And the answer will frequently be “Well, no, I necessarily had to lie in writing.”

In addition to the more concrete reasons, abstractly they're getting a bit of extra usage out of the namespace by segmenting it. A 9ZZZ999-type license plate is not just any license plate — it's specifically an ordinary private vehicle (as opposed to a state-owned vehicle or a trailer) that was registered in California between 1980 and 2026, and both of those facts are durably encoded in the number. Notably, both of these are also very human-readable facts, which for most of the existence of the car bureaucracy was extremely germane. The CA DMV got its digital-records act together in the 1990s (this is from memory, it might have been in the Bush years but it certainly wasn't in the '80s and it was a done deal by the Obama era) but there was a long time before that when "just plug it into the DB" was not an option because the DB was a filing cabinet and the query engine was a human digging through it.

The thing you're not taking into account is that every article that exists takes up some amount of editor time, which is why it's good when more people participate in Wikipedia. You are correct that the server/bandwidth cost of almost all articles rounds off to zero. That leaves just the cost in "an actual human looked at this and okayed it," which has different scaling characteristics.
The general notability guideline is another thing that's effectively downstream of "there's not enough editor time to keep everything up to basic standards." If Wikipedia had 10x the editor-hours it does now, notability requirements would de facto loosen, because there would be enough editor-hours to keep the extra articles useful. Seriously, editor time is the major bottleneck of Wikipedia.
You can create a page as an anonymous user. The content and subject is much, more more important than the fact of being created as an anonymous user. If that's the process you want to avoid, there's also https://en.wikipedia.org/wiki/Wikipedia:Articles_for_creatio... but that one is more geared towards people who are already engaged with Wikipedia. An outsider saying "well, someone, but not me, should do something about this problem," is just as welcome on Wikipedia as it is anywhere else.
For most things the talk pages will explain why it is restricted, but if someone forgot to put a notice there, there's also a giant list of "the following topic areas reliably attract disruptive editing and get people angry, so admins move much more quickly to restrict editing than they would otherwise." https://en.wikipedia.org/wiki/Wikipedia:General_sanctions#Ac...
I am going to say a thing I say a lot: please edit Wikipedia. It is easier to do than you probably think! Wikipedia's biggest constraint is no longer money or server space, it's editor time (especially since LLM-based garbage is a force multiplier on disruptive editing that does not have a corresponding improvement to good-faith editing). Any topic area you know about and/or care about can benefit from your attention. Fixing typos is valuable. Adding photos is valuable. Flagging vandalism is valuable. Please edit Wikipedia.
