You are right to say that mobile nodes are stupid, but this is valid for those that don't know too much about LN and these mobile nodes are hard to manage.

I can easily run 1 or 10 Zeus /Blixt nodes with a single channel to my own remote node at home. The home node could act as a cental bank with public liquidity and serve multiple family members with 0-conf trusted channels in their mobile nodes.

Yes, is a different scenario than Lightning Pub but works perfectly fine.

For the moment these mobile nodes are a good option even for not so advanced users. The trust in a LSP is the same trust as using the same LSP with Lightning Pub.

I have more trust in Olympus, Blixt, Megalith than any random Tor shity node. Let's not forget that these LSPs main feature is to provide good routes for private nodes. Their business is not how to rug pull but to have as much traffic possible to earn more fees.
