Yes, but in the case of Uber there is an option for scalability. If the prices are in surge for a longer period (meaning there is increasing demand), more people will sign up to become drivers because it's profitable.

Bitcoin at 1MB hard cap has no such option. I agree that the priority based on fees is a good thing for the occasional peak in the number of transactions. But not if the system is at 100% percent all the time. All we can have is about 3-4x as many transactions than what we have today. And that's it.

How would you solve the problem? Or do you think this is OK? Bitcoin stays at 7 TPS forever. And only people willing to pay the fees can use it.

In this case you have answered the question of why we need altcoins Wink

sidechains?

Yes, third party payment providers and sidechains are the solution for the mass adoption (by mass I mean your 'can hardly use a cell phone' grandma). But you have to put your trust into the security of the payment provider and/or the sidechain. Let's face it: private keys are safer in the hands of a trustworthy third party than your grandma. But many are unwilling to trust anyone else...

I still feel the main blockchain will need to increase the hard cap at some point. Not by a lot, to prevent bloating, but still... We could put rules in place that would safely raise the limit higher if we really need additional transactions on the main blockchain.
