I think justifying things with “because he was a hermit” can only take you so far. Luke’s beef was with the Jedi, not with the force, his intention in the first lesson was to teach Rey about the force, Jaded luke’s philosophy comes in the second lesson when he talks about the Jedi being a failure, Even Rian said that Lukes goal was to stop the constant cycle between Jedi and Sith rising to power - so by taking the jedi out of the equation the Force will choose someone worthier to take up the mantle of the force.
It’s all meaningless though because the idea behind it is fundamentally flawed.
