"I've never had the opportunity to work with physical labor"
Yes you have. You could go out today and find a job doing physical labor unless you are significantly physically disabled. It's not like there is an educational barrier to all of those jobs. (Yes, I know there is to SOME of them because they require skills and performing physical labor)
As someone that has done plenty of both, you aren't contributing anything to this discussion unless you try it.
Sure, that money actually paid people to do work and those people were then able to stimulate the economy, pay for their education, all that good stuff.
But that same money could have been spent to actually do something useful and it still would have had that economic impact.
*And now I see where everyone else already made this extremely obvious point.
I believe you can buy hubs that are single speed and then if you flip them are fixie, might be cheaper to put that on a cheap bike than having a kid...
I'm a bit rusty, but I believe the way NTP works (at least the reference version which is commonly used) is that if a client sends too many requests in a short time, they are ignored except to reply with a "back off packet" which is called the KoD (Kiss of death) in NTP terms.
Security audits have found some issues with abusing the KoD so I'm not sure if it still works like that or if it tends to be disabled. (I was on one of the teams doing the audit, I found the "Skeleton Key" defect)
You're going to encrypt publicly accessible sensitive data with a 9 digit number ? This is not even close to the current level of security. You don't get to make millions of guesses when some dumb website or clerk requires your SSN to do something.
To decrypt data you get to guess over and over again. An SSN would be a terrible key for that.
Then it should also be noted that you really shouldn't use telnet to interact with HTTP or SMTP either. Telnet has issues if you send control characters, which wouldn't be used for either protocol, but might exist in embedded data you might want to send or receive. Just use netcat.
If we actually included the externalities of coal, the damage to property by acid rain, the health effects, the tearing the tops off our mountains to strip mine - then we could see things like scrubbing sulfur out as efficiency improvements.
