You can't say it is a settlement layer in one breath and then immediately turn around and say that no really everybody truly has access.
The current mining payout is 6.5BTC per block, or roughly $350,000. We are fitting around 1,500 transactions in a block, meaning each transaction costs $300. The price will only rise as more miners join and there is more demand for space in a block. The international poverty line is such that a single transaction would cost somebody at that line half their year's wages.
All that good stuff won't be available to the masses. Just the rich and powerful. Hooray.
Isn't it per 89 years? So basically every person gets one transaction in their lifetime. (If we are generous and allow for 5 transactions per second, then everyone can make 2 transactions in their lifetime. Yay!) That is rather remarkable.
(1500 transactions/block * 6 block/h * 24 h/d * 365 d/y / 7e9 person = 1/89 transactions per person per year)
This is the big reason why I don't buy the lightning network. It won't be possible for people to have a wallet that connects to some lightning hub, since opening and closing a connection requires an on-chain transaction. So it will be impossible for anybody other than the richest few to even possess a useful wallet. Everybody else will have bits in a database they don't control.
This ruins all of the stuff you mention. Or at least restricts these nice features to the rich. People don't have access to these features if they are only used indirectly through the major institutions they work with.
