Running a node in itself does not provide value to anyone else unless they are using your node for broadcasting transactions to the rest of the network, or to see what a good fee rate is, or to provide balance information for the UTXOs they control.
Even the argument that running a node protects against malicious changes to Bitcoin or against invalid blocks being added to the chain is only true for those who rely upon that particular node for their on-chain transacting.
The only other way that you can really provide others value by running a node such that they should pay you for it,is by providing routing liquidity for transacting on Lightning and guess what, you can charge a fee for that.
