I think the biggest mistake many people do is that consider LN as to be an offchain of Bitcoin mainchain. And that is where many fail to understand that behind all those LN channels and liquidity there's a huge incentive to move CAPITAL not sats, as units.

And moving capital have a cost. Cost in fees and another cost in knowledge of how to move it efficiently.

Is this actually hard for newbies? Totally yes. But in the future will be much easier. People must learn, otherwise will get dumber and dumber. making things easier for newbies, it doesn't mean that we doing it better. Bitcoin must be a selection: those who do not want to learn, will use custodials, those are smarter, will use self-custodial.
