This is more like a real scenario. A $ 1000 channel means that you have to pay the hub $30 per year.
Maybe it's more realistic the hub won't earn $30 per year from a $1000 investment. It's not as if there's a shortage of people hodling Bitcoin, but the problem (and that may be a much bigger problem) is that LN-nodes can't use cold storage. If you have 1000 Bitcoin and you could safely increase your stash by running a LN-hub, you wouldn't mind if the revenue is small. It's still better than nothing. But switching from cold storage to a hot node isn't going to happen for a small profit.
8 cents per transaction-this is already comparable to transactions in another blockchain. For example, take dash. There are instant payments that can be made for ~10 cents per transaction. And at the same time, you don't need any centralized hub, you don't need channels, you don't need a third party to replenish the channel. The question is, what will users prefer?
People prefer Bitcoin. Almost all altcoins are solely created for the purpose of earning the creator more Bitcoin, just like tokens/ICOs later on and no doubt the whole Defi-hype that's currently being blown up.
For example, how will 90% of customers use LN? How will 90% of sellers use LN?
My guess:
Customers will use custodial wallets, just like many people hold their crypto on exchanges.
Sellers will use payment processors.
