Banking is a requirement for businesses to function. Depositors have no choice but to put their money in
some bank. It's debatable whether depositors ought to take a haircut or be made whole if their bank suddenly fails. The greater the perceived risk of deposits being held at a bank being worth less than 100 cents on the dollar, the more flighty deposits will be. Even if depositors got back 90% of their money, the concern with SVB was probably more about how long companies' cash would be inaccessible. Perhaps some of the hubbub the weekend SVB failed could have been avoided if the FDIC was able to have some sort of policy to release immediately not only the insured amount, but perhaps also some "safe" percentage that is expected with some confidence to be recovered, like 50%.
Meanwhile, over in crypto land, choosing to gamble on the volatile price swings of speculative digital assets (aka "magic beans") in a market driven in no small part by people evading laws—whether it's illicit purchases, money laundering, ignoring securities regulations, wash trades, pump-and-dump schemes, etc.—is a completely different matter.
It is still, in a certain light, sad that someone would become unemployed because their crypto startup employer's capital was lost in the collapse of a fraudulent exchange. Or someone lost their life savings. But really, what did you expect would happen?
While one could be less sympathetic of small business employees losing their income due to a bank failure or more sympathetic of a crypto user losing their life savings, they're drastically different circumstances. I don't see how one could expect people to either take a blanket "save all depositors and gamblers" nor "all depositors or gamblers should lose everything."
Keep in mind also that practically no one has argued in favor of shareholders in SVB getting anything but a 100% loss on their equity. If you view crypto people as "investors" then there should also be the expectation that one of risks they are taking by "investing" in magic beans is that whether or not they turn out to be magical, the place that stored them may unexpectedly blink out of existence.
