Again: this is huge.
no it isn't
any statutory precedent is meaningless if it cannot be enforced (and hence such things are in no way any kind of law at all).
take the Mt Gox case, the Japanese law firm who are handling that case simply cannot hope to refund all of the 650,000 BTC that was stolen/embezzled, even if cases like this resulted in deposit insurance requirements, no insurance company could even dream of underwriting such a liability, the risk is simply too high.
Bitcoin private keys and blockchain enforcing their ownership are a law unto themselves, that was Satoshi's clear intention from the very start
