Even with the reply you got, you still didn't get it?

Tx fees as pure market demand. You cannot expect something with the same offer (block size limit) and with high demand, to be cheap or nearly free. The speed is also a result of the same factors. Either you have it decentralized and things take longer at peak demand times, or you centralize in favour of speed.

Either way, at scale base chain will never be a good layer for small size transactions. Use LN for that.
