I like having a one hop instant transfer to kraken to sell out for fiats. If there was a site like amazon with LN and one pays through it a lot it would make a lot of sense also. But you do have to have another channel somewhere to do bigger payments, and then pay for having that rebalance.

For regular payments to one address repeatedly, you get fast confirmation and since it is a spending account submarine swap to fill it up, spend to empty it out. Or a second channel with a much bigger balance than the spending one as security but also for rebalancing, you might say "recharging", since it's like an account, in a way.

I'm sure with time better ways to do things and better tools to do them will emerge but for now I'm using LN for my main money flow trunk artery, backed by a few on chain tx's each month.
