Sure, it won't go to literally zero (unlike stocks; companies can go bankrupt). But the difference between falling three orders of magnitude vs. six, say, is not a very big difference to anyone who bought in at current prices.
I'm guessing there's at least someone that'd pay a few million for all of Bitcoin, so maybe a $0.10-1.0 floor, easily? Would be illiquid and hard for small holders to sell though.
Also, quantum computers do not break Bitcoin entirely as in previously unused addresses are safe. You'd need a way to quickly generate keys matching a certain hash. Otherwise you need a ton of hashing power, too, to rewrite the part of the chain created in the time a spend-of-interest was created and you generated matching keys with your attacking machine. Seems like something that can be upgraded assuming a QC-resistant crypto scheme exists.
