That makes sense but it's usually a static number like 10 or 100, especially if it's a small channel. What I'm saying is that these are not sustainable if we have to close them.

LN seems like economically requires people who hold a large number of BTC to make big enough channels that can counteract the price of expensive on-chain TXs. If Bitcoin's future is only full of people with small amounts of BTC and all on-chain TXs are extremely expensive, I don't see how everyone can participate economically.
