While I agree those are all issues, there is no technology without tradeoffs. I personally don't think that those make lightning unusable or even especially difficult, and they are problems which exist with lots of internet technologies.

It will continue to get better and different layers with different tradeoffs will start to be more popular. 5 years ago, there barely was a lightning network. Now, it likely accounts for the majority of Bitcoin transactions (not by volume obviously but by quantity). 

For better or worse, probably over half the world is waiting until their bank offers a Bitcoin checking account before they decide to try using it. And that isn't because of a small blocksize or high fees, blocks are basically empty right now. So let's not break a good thing.
