First of all, I share your sentiment, and I hope that one day most people will choose to use non-custodial solutions of their own volition. Still, I disagree about not recommending custodial solutions at all.

You said recommend, so I assume you're talking about people who are new to the space. Whether talking about lightning wallets or other crypto wallets, I think it's essential to keep human nature and psychology in mind.

Naturally, most people will go for what's convenient and straightforward. They want something with a nice UX and not too much hassle. Therefore, they'd much prefer a custodial solution over a non-custodial solution. They are often just easier to use and offer the features people want.

Trying to force a non-custodial solution on people might actually be off-putting, and it can lead to a negative first experience with Bitcoin. Perhaps they can't figure out how it works, or something goes wrong. Whatever it is, they might get frustrated and give up on Bitcoin altogether.

Having said all that, I think it's essential to educate people on why it's not a good idea to store a lot of money in a custodial wallet and what the difference is between custodial and non-custodial. However, most of us started with some kind of custodial solution and gradually obtained more knowledge about Bitcoin and wallets.

So, the custodial solutions can be kind of a ''gateway drug'' to non-custodial. Additionally, I don't think having a mix of custodial and non-custodial solutions is bad. It is, however, important to be aware of the risks (and benefits) that come with both.
