As Loyce has pointed out above, the Netherlands tried to implement such address verification nonsense.
In a way I'm surprised taxes don't ask for this information yet. They want to know your total balance of everything, and specifics for each bank account, but they're not asking about Bitcoin addresses yet. That's probably because their system can't handle it, but at some point they'll no doubt be that intrusive. It's already a security risk having to disclose what you own, especially considering how many tax employees would be able to access this data.
I am disappointed Trezor aren't fighting this instead of implementing it.
Hense the kuddos to Bitonic, they fought this in court and won. Unlike many other companies, they don't like having to violate their customers' privacy.
It is absolutely crazy that the community as a whole is OK with this kind of insane privacy invasion.
Not only the Bitcoin community, it's the same everywhere: barely anyone cares about privacy.
