Ok, I got your point. I don't feel afraid of Lightning being abused by major institutions, because L1 is open and permissionless, so there will always be an open financial market. You'll never have to put your money in the hands of people you don't trust. Reputation will matter.

I believe you are right. Reputation will likely be very important on Lightning.
You're probably right that the open nature of L1 makes abusing L2 much harder. The more pressing concern I have is that if an individual doesn't have the future equivalent of a good credit score, the large institutions may not wish to take a risk on them. This isn't malice, it's risk management.
Eltoo channel factories would probably make reputationeven more important. They do allow for even cheaper payments in theory, possibly alleviating the burden of holding your own keys, but now the trust model expands to more than one counterparty. One person could refuse to sign new balances and potentially force close a channel factory with twenty individuals.
The politics of managing nested multi-party payment channels is even more messy.
