I think most people will use custodians, many people disagree with me on this point, they are wrong tho

Only the most hardcore bitcoiners will run their own nodes, and this is ok imo 

 I am not sure how they could disagree with you. 

If we are talking about true mass adoption self custody bitcoin on lightning does not scale to the world. 

 Bitcoiners are delusional people and slightly autistic, trust me, I am one
