Except for those third-parties, you mean? The people running the Lightning network are essential to this system functioning and very, very few people won’t be fully reliant on a bank to store their Bitcoin — especially after the first time someone makes the news for losing their wallet.
The third-party can't steal your Bitcoins. Assuming your node is online 24/7, you can verifiably cash out your Bitcoin on the blockchain at any time.

Your Bitcoins can't be stolen by a third-party, unless you and your watchtower fail to broadcast a transaction with proof there was a channel transfer.
That sounds like a lot of infrastructure which you need to operate to avoid trusting your back. Do we have any reason to think the average Salvadoran wants to do that? If not, it’s not exactly realizing the sales pitch.
