That is no argument. Not only you're again dismissing it based on opinion alone, now I'm being personally judged for it... I'm not going down that line.
Practically every research study on happiness associates it with health, family, culture, friends, purpose, religion. Comfort, physical goods, wealth are always at the bottom.
Living in simple conditions doesn't mean forfeiting health or basic sanitation. The question is still valid: you have a home, clean water, a surplus of food, friends, family, sanitary conditions, access to healthcare; but no TV, Netflix, car, laptop. You'll never afford even a mobile phone. Are you poor?
If not having internet, a phone or computer has a detrimental impact on your quality of life - which it most likely does for the vast majority of people who live in the city, have a normal job and bills to pay - then the answer is yes. If you go homeless, hungry or sick because of not having one of these things, yes. But what if it doesn't? It's not as black and white as you imply. This is much more of a philosophical question than socioeconomics (or marxism).
