Bitcoin requires fees to compensate miners without a tail emission. Bitcoin requires congestion to develop said fee market.
Lightning was meant to scale Bitcoin. If you are correct in that Lightning requires the Bitcoin network not to be congested and if there's no solution to this within Lightning, then Lightning is flawed and something else is needed.
Otherwise, get used to it and improve Lightning so that it works. If it cannot work, abandoning it is the right move.
There has to be a fee market, but it should be aligned to the monetary case. The problem is the incentive difference between storage vs money. The storage users can outbid because they don’t care about total loss of value. We must address this, possibly even increase the block size.
