That would destroy cryonics companies who make money via insurance that depends on people legally dying.
Wouldn’t it just shift to health insurance in this case? But generally, yes, recognizing cryonic patients as alive has a lot of legal ramifications. On the other hand, it provides a much better protection against unfreezing: just like with the patients in a persistent vegetative state, someone authorized has to actively make a decision to kill them, as opposed to no legal protection at all. I’m not sure which of these is the net positive. Besides, that would challenge the current definition of death, which currently basically boils down to “we positively can do nothing to bring the patient back from this state”. Including potential technologies in the definition is a rather big perspective change, that can also have consequences for vegetative patients as well.
If I understood it right then vitrification is done to prevent ice crystals from forming. Do you mean something different?
As ZankerH mentioned below, vitrification leads to cryoprotectant poisoning, which is a sufficiently big problem to prevent us from experimenting with unfreezing even in small organisms. If the function of the cryoprotectant can be fully or partially replaced by keeping the sample under the high pressure, that problem is mostly solved. That doesn’t prevent crystals from forming, but unlike normal ice, these crystals take less volume than the water they were made of, so they shouldn’t damage the cells. In addition, amorphous solids aren’t guaranteed to be stable, and can undergo slow crystallization. I’m not sure how pig of a problem that is for cryonics, but in case of going directly to ice-IX, that’s definitely not a problem anymore.

Health insurance doesn’t automatically pay for everything.

A bit but not that much. A company that can’t afford to freeze would still shut down. Nobody is foreced to pay to keep the machines on in every case.
