People who are getting paid in BTC for their work. I know a guy who earned $2,000 in BTC in one month, in August 2016, for creating a poker site. There are many others earning smaller but still significant amounts, for example here, participating in Sig campaigns.
Hmm,
If people like me quit buying BTC because of ridiculous fee system, who is your friend going to sell his BTC to , when he needs to convert to fiat.

Higher Transaction fees will be everyone's problem, not just mine.

I agree and I'm really grateful to you that you are from the ones who is buying BTC. I'm not saying that ridiculously high fees is not a problem I'm just saying that around $0.5 is not ridiculously high and lately we are having around $0.4 for a median transaction size so if it stays more or less on this level I'm okay with that.
