If you go offline for a week, you can't receive transactions for a week. Connect to a node that processes a million dollars worth of transactions per day, without securing the channel on the other side and congratulations you've invented a bank (albeit fractional reserve spending is more difficult). Not that that's a terrible thing, I mean it's better than most banks: I've used it before as a means to transfer money from exchange to exchange: it's competitive and has low fees compared to SWIFT. But the problem is that if people rely on some centralized payment processor you will eventually get vendor lock-in. You have that now with Coinbase commerce: before it was the case that they would just give you an address and you could pay with LTC or whatever, now they want you to download an app and link it with their system. That's the direction all this LN stuff is generally going.
