Fees of 700+ sat/B is unsustainable.
Bitcoin price at 20 000 USD is too high ... too ?

Bitcoin is a network, if you want it ... pay the fees.

I do not understand how this can be a counterargument.
If the price increases to $ 200k, should we expect fees of 7ksat /B?
Networks are maintained and expanded because they are useful. Each time the fees increase, the network progressively loses utility and its network effect.
