I think you have to get with the times a little. Crypto is an asset (some coins a security) and has been recognized as such under the law for several years, and it's taxable.

Crypto is on the balance sheet of individuals, businesses, financial institutes and even at least one nation (El Salvador). There's crypto index funds and ETFs trading on wallstreet.

And here you are philosophizing about whether crypto can really be owned? You're a decade too late.
