Yes, valid points. Lightning nodes as they are now are generally not for people who have never run another type of server at home. Lightning needs constant innovation and improvement.
But in general, I don't think the problem is 100% solvable. If you look at bitcoin miners - they are totally nicely plug and play. But then the hardware is not universal and very much centralized. We depend on the few producers. So to achieve decentralization, there must be a significant element of "do it yourself with nails and a hammer".
