Why is this even an argument against LN? Most of the internet requires both parties to be online, and billions of devices are online about 99.9% of the time. My debit card also requires both the shop as well as my bank to be online when I make a transaction. That's not a deal breaker.
And even though Bitcoin can work when the receiver is offline, it still requires both parties to be online and verify the transaction to complete the sale (or whatever deal we made).

I can only speak for myself, but I've said it for years: I don't really care how, as long as Bitcoin does scale! I wouldn't mind bigger blocks (I think it was 32 MB per block when Bitcoin started), but that caused a lot of drama. High fees aren't good for adoption, and although I agree with the argument that Bitcoin can't reach mass adoption by storing billions of daily transactions on-chain, I also think it would be a good temporary solution to allow more transactions until a more permanent scaling solution is created.

@Warless: This isn't the place for oneliners without arguments.
