Not a technologist or a programmer, just an independent trader, so if you can bear with the technological ignorance revealed here, I will try and not be too vague.

Recently I was reading about the transition to a "cashless" society, which of course got me thinking about government surveillance, and then logically about the claims of the Austrian-type of Bitcoin believers. I am not myself in this camp that makes claims about financial sovereignty and sound money, but I do sympathize with libertarianism on an ethical level.

Now if governments do find that they have to clamp down on cryptocurrency it seems to me that they would have to do so at the level of infrastructure and hardware. Around the same time that I was thinking about this, I was also at hard wallets.

It got me thinking that despite being digital and a network, Bitcoin could in some sense, to the extent that it exists outside government controlled/regulated infrastructure, constitute a new form of cash, that is if hard wallet technology can facilitate easy interactions. Is there a sense in which cash might be able to exist in technologically evolved form?

This idea must be out there already, and I am probably just behind in what's going on in hard wallet technology, but it seems to me like that could be the key to cryptocurrency's being a viable alternative to centralized digital currency/social credit/tyranny.
