Just like it can be extremely fulfilling to build a PC from parts, compile your own Linux kernel, get an old car working again etc., it can be nice to have somebody else do all of that for you and focus on the details of life that you enjoy most.
It's actually good to offer more options to invoke curiosity, but the old options are still there.
Nobody has to do this in any city I have been to. Even in the most hipstery independent coffee shops, you can still ask for a black/white coffee and they will make you one. And if you simply can't stomach the independent coffee shop there is most likely a Starbucks or Pret next door.
Granted I have not been to Iran, and am loathe to make assumptions about countries I have not experienced, but I simply do not believe that OP cannot find a "basic" coffee in his city.
I'm sure there is some influencer/performative aspect to this as well that the author is reacting to, but the complaint strikes me mostly as a "I was ok with the status quo, and I dislike that other people prefer things other than that". Having preferences and choices is not by default some sort of pretentious thing!
I agree with this guy. Teheran is probably a nice place if it weren't for the ayatollahs, hijab police, sponsoring terrorists, embargoes and "friendhip" with Russia. All those details are like coffee marketing made into a religion and used as state policy.
