It still does make sense considering that russia is literally invading Ukraine (at least once a decade…) and continue to probe NATO nations. Because, in that regard, it is less a “military base on foreign soil” and more just a NATO base on NATO soil. And, in theory, it is a good idea to let the country dumb enough to spend most of their GDP on a massive standing military to foot the bill.
But considering that the US is just as likely to be on russia’s side in WW3…

De facto, no.
Yes, there are still some services where there are absolutely zero questions asked and all you need is a prepaid card that doesn’t need to be activated at all. Those are quite rare and have a very limited number of phone numbers allocated to them and pretty much are all flagged as spam/bots by every single system out there.
The next tier up are services where you technically don’t need to provide any ID to use a prepaid card… but the store you purchased it from needs your ID/credit card to activate the card when you buy it. Those ALSO tend to have the same problems with burned numbers.
What most people have as burners these days are just the same phone service as anyone else. They just pay a rebranded t-mobile at the start of the month rather than the end of the month. And those have all the same restrictions, and capabilities, as “real” phone plans.
