"onchain will not be for everyone"

Suppose I have a friend named Jimmy who is one of the people for whom "onchain is not for them." How should Jimmy use bitcoin? It seems that lightning requires the ability to force close i.e. do an onchain transaction. If onchain is not for Jimmy, how can Jimmy, how can Jimmy force close? And if Jimmy cannot force close, how can he use lightning?
