> Why should a law-abiding saver bail out what in many cases looks like a gambler’s foray?

Because having an idea about how these frauds are committed are helpful for society as a whole. Law enforcement investigating such crimes is the first step towards meaningful laws and regulations.

Acting as though these crimes never happened because they're not enshrined somewhere in the criminal code is cutting off one's nose to spite the face. The negative externalities will still be there, and they will land squarely at society's doorstep. We will all have to foot the bill one way or another.

Everyone's a rugged individualist until they get rugpulled.

I am not sure what you mean by “bail out”. When something gets stolen from you, the government doesn’t repay you for the actual amount. They do pay to litigate/make litigation possible. That is part of the societal contract - if you own something and someone takes it from you, the court system exists so you have legal means of restitution. I don’t really care about whether that’s good or not to apply to crypto, I am merely pointing out that it does.
