Why use a custodian if you have a node?
The whole point of my note is that everyday users can't run nodes. Not only technically, but there also isn't enough blockspace for that.

You can setup a simple node, ie with only one channel to WOS, you can send and receive through their wallet. You donβt have to worry about channel management and can just use it to spend. You can move extra funds to your node for safekeeping when needed
This still makes no sense. You can just send directly from your own node without ever using their wallet and having them custody anything. One channel is enough . If you don't have liquidity to receive directly then you wouldn't be able to send sats back to your node from that channel. If you do have liquidity then you never needed to use them in the first place.
And again, not everyone can have a node with on-chain channels so doing this round about thing you're talking about is moot anyway to the point I'm making.
