Learn more about LN, seems that you lack of knowledge about it.
how do I close my LN channel without paying a prohibitively high fee?
You don't. You keep using a LN channel as much as you can, not after each payment.
p2p pooled liquidity borrowing and lending
That's stupid. In a Bitcoin world you are forcing users to go back to use crapcoins or fiatcoins. Bitcoin is savings technology, not fractional crap reserve. You save sats until you are able to buy what you need and you buy only what you really need. You don't have enough BTC? Fine, work harder until you get them.
You can't lend/borrow more BTC than you have.

What happens when you can no longer use the channel? Without the ability to settle on L1, do you think LN works at all?

That's a strawman, LN requires opening of channels, but closing them really is optional. No need to settle if you continue to maintain the channel. It is conceivable that the open-to-close ratio of channels will get very close to 1 over time, a channel could become something that you can pass on to your descendents, if both sides are determined to do so.

If everything is working as intended, sure. Seems like many people are overlooking the concept of being in an adversarial environment.
