So you think that if you buy a $2 coffee in Starbucks this transaction should be registered in all computers running bitcoin in the world? Inegociable?
I think with rising storage capacity for a more and more cheaper price this is not an issue. If you want to create an internet currency or whatever Bitcoin is you will have to live with the fact that people use it.
Still I get the point of lightning etc. , I just think that Bitcoin should solve all of this issues. But definitely you can have a different approach to that.
