The majority of lightning node runners will have much less then 1 BTC. So it is more like "support the network". There need to be many nodes to avoid centralization. Setup and running a secure node is difficult enought and stops zhe majority of bitcoiners to have an own node. Let alone all the lightning managing stuff.

On the contrary, I think it makes sense for everyone to run their own small node to pay vendors for goods and services via Bitcoin Lightning through their own node, and also, if needed, to receive payments from others. The benefits are that a person controls their own funds, maintains privacy, and incidentally supports the Bitcoin Lightning network if it's a public node.
Or, for businesses to run their own node to receive payments.
These two scenarios seem most optimal for people who want to work with the Bitcoin Lightning Network.
But running nodes solely to earn commissions from routing, I think probably makes no sense.
Maybe a third option is to become an LSP provider and sell channels automatically, if such support is added to major wallets like Breez SDK, or Zeus, Wallet. Here you can earn from selling channels, and this will likely be more profitable than earning from monetization.
Ok, so we understand it the same way. However, running an own lightning node is way to complicated for even avg. IT person. I hope this will increase.
Have a own node with maybe 5 channels requires already 6M sats to be save. This is only enought for small payments in US and EU standards. Smaller channels could be risky if fees grows massive in future. Beeing to high to have small channels running.
