I agree that end-users cannot handle micro transactions across the whole internet. That said, I would like to point out that most of the internet is blanketed in ads and ads involve tons of tiny quick auctions and micro transactions that occur on each page load.

It is totally possible for a system to evolve involving tons of tiny transactions across page loads.

And, the whole internet is already micro-transactioned! Every page with ads is doing a bidding war and spending money on your attention. The only person not allowed to bid is yourself!

Clearly you don't have the lobes for business /s
