Yeah having a house 3x the size is not great for you or the environment, given that people don’t use most of their houses ;-)
I wish people here would stop telling me what's good for me too.
Whether that’s important to you is - as always - completely up to you in this country. I don’t understand the animosity between different states; we can all go wherever we fit best and that’s a great thing.
Nothing wrong with wanting a big house, but also nothing wrong or coercive with mentioning it has environmental impacts
When something affects you personally because it is forced on you it is much harder to be tolerant.
If it only affects the people who want that law then it is much easier to just say "I do me, you do you".
Different states are supposed to have different ways of life based on different value systems. That way people can move to the states that are most in alignment with their values. Laws at the Federal level take that freedom away.
Who are you to cast stones?
