Why do you take that for granted? Bitcoin fee income levels (even the sustained ones outside of the recent traffic) are many times the entire fees PLUS subsidy of several competing altcoins combined.  Are they currently screwed?

Guess you don't live in an area where comcast has a monopoly.

What "use case" are you referring to?  A description of a use case should not mention Bitcoin-- it should mention a problem people have which Bitcoin might be a solution.

I'll give some examples:  "My bank is only open for international wire transfers from 11am to 3pm M-F and I want to be able to send money internationally at any time." Bitcoin solves this.  "I tried using online payments but Paypal froze my account randomly with no explanation and wouldn't give me my money back for a year" Bitcoin solves this.  "I wanted to hold on to money but my government keeps printing it like its going out of style, debasing its value" Bitcoin solves this.  "I wanted to buy a telescope but I couldn't convince my bank it wasn't fraud and they froze my account" Bitcoin solves this. "I wanted to buy provocative comic books, but even though they are unambiguously legal where I live, the government leaned on payment providers to deplatform the vendor" Bitcoin solves this. Each of these cases Bitcoin can help with because it removes trusted third parties from the process of either transacting or storing your wealth, trusted third parties which otherwise could capriciously interfere with your right to associate with others.
