My #1 reason is that once someone figures out how to build large, reliable quantum computers and program them in a practical way and quickly break sha256, bitcoin might be how we find out. That still seems to be a ways away though, and in the meantime, having a mostly-unbreakable digital ledger seems to be valuable.

AFAIK a practical quantum computer would not enable any practical attack against SHA256.

My main reason is because if BTC became mainstream a bunch of crypto nerds would become richer than many banks.
No way they'll allow that to happen I think.
There's of course also
- deflation meaning anyone who believes in Bitcoin and uses one to buy something is either desperate or a fool
- as well as practical issues like energy consumption
