With all due respect, I'm neither "responsive", nor "expert". Moreover, I prefer to piss in dedicated directions. So, I understand that Your "you" not addressed to me.
I'm trying to run small closed social network and from 300 users I received 400 complains that they want to access it from cellphone. May be they are fool and know nothing about how good site (not for idiots - in Your words) must be operated, but they know very well how they want to use it : immediately, see more tens times per day, in bus, in park, in bank or store - get news, comments, updates etc. "Responsive" layouts doing it badly, D/app - worse. So, for me, in current time, in today's conditions - Resp is the solution. Yep, partially, temporary, poor and ugly. Btw, do You know better one?
