It would be great if there will be non-custodial solutions on higher levels of bitcoins. Especially because I don't see how on earth it will be lossible for everyone to even get any number of satoshis on layer one.

For many in Africa, Asia and South-America the first layer won't be an option, but holding bitcoin with a trustworthy custodian will still be a solution for many to get out of the inflation prison that their  local currency puts them in... 

 Agreed. My hunch is non custodial lighting wallets is not the solution, lost hope of that. A sidechain such as liquid seems good but as its not being used I am assuming people don't like the tradeoffs on that either.
