Yes, we will clearly continue to be able to fit 10 minutes worth of transactions from a global populace into two-thirds of a floppy disk for the rest of forever.
Fees alone will not solve scalability. If you honestly believe that then you don't understand this system as well as you claim to.
Here's an honest question to those who advocate keeping a 1MB block: how long would the backlog of transactions have to get before increasing the blocksize would become a viable option in your opinion? I genuinely want to know just how far you're prepared to cripple the network to justify your agenda.
I love Bitcoin so of course if there was a problem I'd support the fix. There simply is no problem though. Spam attacks helped prove that, transactions increased by insane amounts that would never happen naturally and network still ran fine.
Please explain how increasing fees will allow the network to scale beyond 7 transactions per second?
(For the sake of argument I'm assuming that the current capacity limit is 7 TPS which seems to be a widely accepted number.)
