Scenario #2.
Lightning network runs the way it is ultimately designed. Huge spider web that connect everyones channels. I have channel with my friend, he has 1 with Starbucks. Multiply this to everyone and every store.
Sirens, huge problem. To hop thru other ppls chsnnels you have pay a fee, more importantly, their channel and every channel you hop thru has to have that balance of btc or higher.
Huge huge prob.
So private depositories will open up that have huge reserves, open a channel with them, they take care of rest as they have the funds and chsnnels with every store in the whole world.
This my friends is centralization. Give depository, 1btc, they give you back lightning ious Sound familiar? Depository says give use your gold, heres paper ious
So lightning for sure is a fix. Its just a full blown centralized digital currency.
