So many others have said it, but I will throw my 2 cents in: I disagree with the premise.

I think there could be a way of going camping that would be 'playing poor' -- if I went and set up my Taj Mahal tent on the side of the highway exit where a number of homeless have set up their tents; if I camped (illegally) in the parkland near my home, where the homeless set up tent cities (until the cops roust them). But if I go to a national park, and camp in the designated campgrounds, I don't think there's any element of 'playing poor'. Is it 'playing poor' if I live in a townhouse when I could potentially afford a McMansion? is it playing poor that I work for the government for 70-80% of what my private sector colleagues make? Is it playing poor if I buy generic brand peanut butter instead of fresh ground, organic peanut butter? (actually, I hate peanut butter, so I'm not sure why I chose that example...)

I recognize that bike commuting is, in many ways, a hobby for me. I have no need to do it, but I enjoy it. It has many health benefits, and it keeps my mental state in a better place. But do I think that the guys riding the clapped out huffys that are riding on underinflated tires should be P.O.ed at me? No. Heck - they benefit greatly from the fact that there are affluent cyclists who push cycling facilities and infrastructure. Likewise, I do my best not to be judgmental when I see one of them riding at night with no lights, no reflective gear, and the wrong way... It still frustrates me, but I don't judge.
