Sorry, I do not understand your comment. Can you clarify. What does "a lot more centralized in practice" mean?
> What's the point of it all in this case?
Lightning is an L2 protocol, highly scalable and used for low cost payment in Bitcoin. Level 1 networks are almost never used for user transactions: your credit card payments do not go over fedwire, etc. Bitcoin protocol is not scalable to serve worldwide money transfer needs; Lightning is. And with the cost of a penny per transaction or so.
> Why not just use regular currency?
There are a lot of frictions in the current banking systems, because money laundering, because drugs, because whatever. Getting $5-$10k in regular currency while on an overseas trip can be a major quest. With Lightning I can transfer that much (or more) in a few mouse clicks.
As a side note, I think the federales are already way too nosy regarding my use of my own money, so I want to give alternative options as much business as I can. My 2c.
Isn't it hard to use in practice? Liveness, inbound liquidity, moving funds between L1 and L2, don't all of those lead to massive use of hubs, this denying the entire premise of decentralization?
Very easy. If the merchant supports it, it is extremely easy; equivalent to pointing your phone at a reader to pay with GooglePay. Between people -- a QR or similar.
This doesn't answer my main concern. How do most people use Lightning? Do they operate on their own or use a big hub?
