So... I know someone with about that many bitcoins. They have never used a notary to sell any coins whenever they want. They have cash in multiple countries in many different banks and jurisdictions. I wouldn't say the notary and police interviews are required.
Isn't it just a tad bit disingenuous to say "those same bitcoins", when, as we all know, their value has appreciated by around five orders of magnitude since then?
In dollars, but purists would argue that's irrelevant when transacting in bitcoin
