You could put an endless series of unique identities on the BIP 32 tree structure. Its personal identity management we are talking about here. This is identity freedom. Identity empowerment.
Right now we are forced to use almost one identity for everything due to technological limits. If you want to get a loan for a house you have to give unfettered access to the entirety of your personal identity. This is the tyranny. Not the freedom that trezor would afford by empowering its users with the capacity to authenticate with the identity of their chossing, without reveling other identities or even if they have other identities.
You could literally have "rep" as a trustful drug dealer. Verify your rep before a client even talks to you so that he knows you arent a cop. Then hand your trazor to a cop and he would have no way of using it to identify you as mr drug dealer. That is like the least Orwellian thing I have ever heard.
Unfortunately, the highly creative slave-masters who use the criminal alias "government" are several steps ahead. Not only are they full of talk about "no absolute right to privacy", but the "pre-crime" concept is actually beginning to get talked up by their degenerate criminal associates (a.k.a by their criminal moniker "policy think-tanks").
Won't give up your keys? "Thought crime" will put a stop to that. These "just-following-orders" types need to actually realise that everyday people can secure their own rights, that rights are not always something that someone bigger and stronger allows you to do.
What do you guys think. Do you think I could make a living as what andreas antonopoulos is to bitcoin except for trezor?
What makes you think Andreas makes a living doing what he does?
For regular world "credit rating" you would need to consolidate everything into one identity though. There's just no way around that. One social security number / tax identification number / social insurance number / driver's license number / passport number. If you're a normal average person who would go through a normal average life, you need to stick to one identity for your home, your credit, your car and any loans from a normal bank.
Why are you creating an association between those different data sets? What is the common factor between them that determines the benefit of associating them?
