Yeah I don't mind a bit of third world adventure, but in short doses, on visa runs. Tropical island, hike up a mountain, etc., then back to first world comforts in a developed city.
I don't think being in a developed city is necessarily recreating western life, Asian cities are totally different and a vibrant cultural experience, I've learnt the language, built relationships, improved as a person, etc. If anything you get to meet more people. Culturally and politically it's a very different country to mine even though it's developed.
Definitely agree that you shouldn't just live in an expat ghetto, avoid the locals and be an economic migrant just here because it's cheap. I spend pretty much the same amount I would back home but here my cash is helping the local economy and small businesses instead of going to taxes back home. Overall I think I've assimilated well and am a net benefit.
I still have that romantic feeling of travelling and 'finding myself' without pulling my hair out at the infrastructure as you put it.
Also forgot to mention Bangkok has $5/$5 live poker games with double straddle, most sit down with $10k buy in
