> BGP is the protocol that gives the Internet its shape, and you can’t directly speak it yourself.
It's actually surprisingly easy to get an ASN for yourself and speak BGP. If you find building something like this tool interesting, you should give it a try. I wrote an introduction of sorts earlier (https://qt.ax/asn) if that interests you.
The whole BGP process with a private ASN that the ISP strips out and replace with their own ASN on the Internet is how "BYOIP" (bring your own IP) usually works.
You don't actually need an ASN to get PI though? You can use PI just fine with BYOIP. Actually... I don't think you are even required to announce them on the Internet.
Note that ARIN NRPM 4.10 now requires the requested range to be used exclusively for IPv6 transition and not anything else.
As for full table, several providers I recommended in the original post are able to do a full table for less than $10/month. You can also join an IX and ask nicely for transit from other members. Some may even offer you free transit the moment you join.
I am curious which leap day system you use for the French Republican calendar. Most popular versions of the calendar I see floating around just use the Gregorian leap year system, which I don't like because it yields the wrong results in the year the calendar was in use. Yet, I don't see mental math as a viable option when using the original date-of-equinox method used during the revolution.
