A lot of the following will, at this point in time, be mainly hypothetical, however, one thing is certain: Your UTXOs will be inherently linked to your meatspace identity.

Further, given the transparent nature of the timechain, you're creating an immutable link between your identity in a fiat world, now, and your Bitcoin position in the future.

When HyperBitcoinization comes to pass, you may be affected - Governments and platforms may censor your purchases - Even if you move to another wallet.

Your UTXOs are tainted and any UTXOs from certain addresses or that have passed through certain addresses may be refused, depending how address-depth sensitive.

Essentially anyone gaining Bitcoin via a KYC method now, *may* be doxxing their future selves.
