Maybe you know something I don't, but switching to an entirely-virtual provider in response to a difficult-to-execute physical threat seems a bit misguided to me.

Google also has notoriously nonexistent customer service. It does not instill confidence that anyone should rely on them for something as critical as identity management. The threat of them fucking you over when you need their help far outweighs the threat of hackers and scammers.

(Virtual money was supposed to be more secure than physical coin. That experiment didn't work so well either.)
