Agreed, and most likely the average user will opt for a custodial solution over something like breez. I've read about the possibility of using Litecoin and atomic swaps as a virtually feeless way to onboard onto lightning, which could help someday... Personally, I'm willing to do the work and put up the capital to use it, but to get mass adoption I'm sure that things will need to be easier. 

That said. In 1995 Linux on the desktop seemed like a pipe dream. Now everyone uses Linux, on their smartphones. Sure, it's Google... But if that can happen, then lightning can happen for the average dummy too.
