I do not see the point of this post. Yes, you outline some cons and pros, but is that what really matters?
For me, what matters is if it has legality and if it is readily accepted by everyone. But for now, those are not yet true in bitcoin.
I agree. Op is clearly trying to prove how Bitcoin is better than FIAT and gold in different aspects and I feel he is right in some ways and wrong in other ways.
Mainstream adoption is what primarily matters at the end of the day.
Bitcoin won't replace FIAT or gold, but is meant to serve as an alternate payment solution IMHO.
Completely agree here. You can make any kind of test with the final result you want... This doesn't prove anything.
Secondly, why do you keep comparing them? Bitcoin will not replace any of the options. It can just simply be another option. Also tokenizied security (or security token) doesn't have to necessarily replace any security in place.
