> you've only had this kind of recourse for the past 50 years. before that, for 5-10,000 years, money in all its forms worked just like bitcoin.

To the extent its true (and, actually, money in most of its other historical forms doesn't work much like bitcoin, but yes there wasn't a widely used convenient equivalent to modern payment dispute resolution systems before credit cards), like computers and modern dentistry and all kinds of other modern developments, its not one of those things I'd like to give up having to go back to the way things used to work.

Can we safely assume you never use physical cash because it doesn't support "charge backs"?

Also, what do you say to the populations of the ~40 countries that credit cards don't work in because charge back requests are too common there? Do you tell them to simply never make online purchases?

You've only had the range of goods you can buy today in the past 50 years(or less), made possible in large part by that very sort of mechanism.

But it worked in person. Not over the internet to someone you will never meet in a state/country you will never visit.

And for how long have we had distance selling? In particular over the internet?
