That is entirely still a societal norm and a statement of personal belief about specific rights. You might believe those rights to be inalienable and that your property is necessarily yours, but that doesn't actually translate to to a guarantee of maintaining that possession in the absence of the institutions that currently protect that ownership.

Anyone who's lived through a massive societal upheaval, collectivisation, dictatorship etc can attest to this - your ownership of property only means anything in as much as it's protected. If the state fails, or if society's understanding of private property radically changes then your investment is only valuable if you can hold on to it.

Even in the private-property loving West the value of an individuals property can often turn out to just be the amount that the state decides to pay them when they seize it via eminent domain.

Pretty sure when Detroit went bankrupt they were basically paying people to come back to the city. There are ghost towns for a reason, because homes do lose value, even for the person who can still live there. Bitcoin right now is in the middle of nowhere like these ghost towns that can fail if the one company supporting them fails or the farmers just give up. It’s becoming a bigger city, to continue the analogy, but is still in the gold rush phase, where all the miners have come out looking for something. Maybe the city becomes San franscisco or maybe we find a ghost town in 100 years once everyone realizes the gold ran out.

Rights are constructs, let's talk capabilities.
