If you can afford a unilateral exit in the first place, you can open a Lightning channel. The scam is that it claims to offer solutions, when in fact all it does is introduce trust and centralization as trade-offs Lightning wallets can use trust and centralization to for better UX, but that doesn't get hyped up by hipsters and investment like the "current thing" View quoted note →

The whole interaction of Ark with the rest of the world is through LN. Yes, maybe they can send some bits and tits inside the ASP, but they will need to interact with the rest of the world to be able to make REAL payments. Ark's wrong assumption is that people will just drop the whole LN and use Ark. That will never happen. That means Ark will be just a niche feature used by such poor users that cannot open a damn LN channel. Fun fact: all those complaining that cannot afford a LN channel are the ones that for 15 years denied bitcoin and some of them used shitcoins. If you would buy just 1000 sats/month during all these 15 years you would have enough sats to open a damn LN channel and do your thing.
