What happen if bitcoin will stick to 1mb blocks?
blocks will start to become filled constantly, fee's will go up, micro transactions will be forced of-chain ( or to complex to really be worth doing ) small transactions (<100$) will be more costly, might get to the point where fees are not competitive ( people start using paypal or the likes to move money more efficiently), suddenly buying everyday things with bitcoins becomes a funny idea, Bitpay will go out of businesses, seeing how a large % of speculation was speculating bitcoin would one day become a use able currency its value will implode, bitcoin will revert to its 2012 state / value, and then its downhill from there as ETH accidentally becomes a better form of currency without silly blocklimit debates stopping there scaling toward world domination.
it was never a great one to begin with.
to OP: supply and demand will economically constrain access to direct transactions on the blockchain. users who cannot afford this access will need to consider other services to address their need. this seems like a huge problem right now because there are few if any of these services available but within next few years plenty of such will be developed. these, while not being as trustless as Bitcoin, will provide greater utility at a fraction of the cost while still benefiting from the trust and decentralization emanating out of Bitcoin's protocol layer.
