This is interesting because on one hand we've got people on one side of the scaling debate advocating for the ability for everyone to have access to a utxo (full/shared) (onchain scaling) and on the other hand, those advocating for 2nd and 3rd layer solutions to achieve scalability.
If one is saying the only way to achieve mass usage of #bitcoin is through layer solutions (exchanges being one of them), then it would seem #Bitcoin in its current state is good enough since most people won't custody their coins themselves.
interesting observing the dichotomy between the two pov.
