To me, it's reducible to the equivalent of a seller saying "I will sell you the answer to 1 + 2." That seems inherently worthless.
It's only worthwhile if rich idiots are trading these mathematical answers around like baseball cards. But then, I don't see how they can "own" them if they or anyone can just make infinite copies of them when/if they ever have access to the "private key" material.
Ownership of the underlying digital asset doesn't make sense either. Again, there don't seem to be obvious legal or technical protections to stop anyone from making copies.
Yup. Effectively, printing their own currency of large denominations and trading in real money for them. Which then reduces to people stuffing real money into ever smaller suitcases for exfil and cleaning, regardless if they're new shiny thing dabblers, corporate pirates, actual pirates, or drug dealers.
