I mean online providers like jmp.chat, my sudo, and virtualsim will hook you up for a couple of bucks. So sure, if you are seriously cash constrained or crypto is unobtainable for you, then not so easy.
Depends, who do you want to shield what information from? Signal knows all of their users’ phone numbers. You can hide it from other Signal users. All depends on your threat model.
How exactly is it hashed? There aren’t that many possible phone numbers, so it might be viable to just try every valid number until you find one that matches
Right, then Signal might not be the best option. The NSA can easily track who’s using Signal, and possibly do some traffic correlation to reveal who’s talking to who.
But to state that there is no privacy on Signal at all is a bit of a stretch.

Basically a app that lock you with a phone, giving you only one account. Centralized servers. Not good.
Good for some use cases. Only if the Signal Foundation stays in the current track and it doesn’t go south like with Mozilla.
For a privacy chat group with random people, maybe another app would be a bit better.
Personnaly I would recommended SimpleX for small groups and 1:1, only a bit less uglier
Because you can’t have privacy if a company asks for your phone number.
Burner numbers are pretty easy to come by…
Not for everyone. Check your privilege.

If you use one of those accounts, someone will just take over your account after some weeks/months
