Very good questions. I think the primary is that some form of workout is very important to your overall health, and you should just pick which type of workout works for you in the long run.
It doesn’t really matter if you get a home gym, or go to parks, or to a gym, as long as you are consistent and have fun. For many people, the gym is intimidating, they might be better off with a home gym. I find the place semi-social, which means I get distracted by people watching, but don’t have to chat with anyone. Works for me.
The key, I think, is to shift from “I can do all of that at home” to “I will do all of that at home.” An insane number of home treadmills and exercise bikes collect dust because the mind is willing, but the flesh lazy. I love the distraction, others love the camaraderie or the friendships you make at a gym. They push you to go even when you don’t feel like it, and that’s the important part.
Americans have so much of their wealth sunk in their real estate / home that they eye any change with deep suspicion and an eye on how it affects their home value. Surely, a 5 story building next to your ranch home is going to lower your home value, so it must not happen.
I think this is a dilemma that everybody in the Bay Area faces: you can universally agree that more housing and especially more dense housing needs to be built, but you can’t allow it to be built near you because that drags your home value down. Even just a 5% drop in value may be all the equity you built if you are a recent buyer.
I guess a compromise might be to give people near these new buildings a property tax rebate as counterbalance. Also, instead of mandating parking, maybe you mandate that people moving into spaces designed to be near public transit not register cars there.
