Personally I don't mind converting fiat into crypto as I also do it the other way around. I have been trading with a trading bot and converted some of the proceeds into fiat.
I understand that the bar is lower when you don't feel you are spending your fiat money, but it does also show the appreciation for the creator, whether it be a product or a service.
When come across a homeless person, would you feel better giving them your own hard earned fiat or would rather give them money from someone else?
Steemit makes a lot of stuff easier and we will see the development of it's uses in the near future. Time will tell
