I think it will not be a problem as long as there are still many people who use eth they will get used to it later.
Transactions must still be made, even if the fees are low or high because the market is running automatically, so that minor problems such as fees will not interfere.
It's more than minor problem though, sometimes people forced to pay the high fee out of necessity and it's definitely better to switch and uses alternative coin but the eth market is just too big to miss out. but defi right now is dumped and the hype probably gonna fade and become normal again. hopefully the fee will be resolved.
