I'm not the best person to answer, but lacking better ones, here's what I know: * LN is technically complex, and hard for a normal person to run. * LN requires making an on-chain transaction to open a channel. It's still vulnerable to high BTC fees and limited by the chain's low capacity. * LN still runs on top of BTC, and has all the economic characteristics BTC has. So if it's stupid to buy pizza for $10K BTC because it appreciates, or stupid to sell a game for 0.0012 BTC because the price might fall tomorrow, then LN changes nothing about that and in some cases makes it worse. LN allows a non-cooperative party to delay things, which could be used maliciously during price swings. * It's all still happening inside the crypto ecosystem, which is unpleasant to deal with. Think of say how people tried to buy their Tesla in BTC, then asked for their money back when the price rose. Why would a merchant want to deal with that kind of thing? LN to me is a bit like putting lipstick on a pig -- it still leaves many significant problems in place, and adds some new ones on top in exchange for the benefits it provides.
