I couldn't answer that question well. I already see a benefit in a hosted Lightning Node. But most people probably still lack use cases. The hosted node must bring an advantage of other wallets. The question is the use case, the price could be based on it. For example: with a VPN subscription I can not only surf anonymously, but also bypass country blocks.

yeah, the ultimate question is if there will be use cases that are impossible with the legacy world. We see some exciting, but that whole ecosystem still has to grow and it takes times.
