No, it definitely scales better than bitcoin and is faster (although not truly final settlement, but maybe that's good enough).

The trade-offs to use it are major atm. You either have an easy experience (and lose custody) or sovereign LN usage (and lose UX = less adoption). A smoother experience on LN requires more centralized hubs = less failed payments. Onboarding everyone would also take ~40 years iirc. And many other things...

I have no solution, just pointing out the problems. @Polyd_ and @4moonsettler are trying to solve this with Enigma, Darkpools, etc and make LN less user facing. Validity Rollups? Drivechains? There are many other alternatives. Not sure which if any will win. Maybe LN gets scrapped eventually who knows.

Monero has it's own problems too.
