The main point is people worrying about resources and how to allocate them. We are creatures who want joy and I will not apologize for that. Certainly in face of abstract things such as "the environment". Which environment? I am a humanist. That definition varies. Golf is not the problem sorry to pick on it!
The fact is, at this point there is so much demand for DC capacity that the prices are super high, and thus it's worth building them. Many people believe that it's a bubble or whatever. If they're right, well then a lot of people building DCs right now will lose their shirts. If they're wrong and the demand is sustained, DCs are exactly what we need to be building.
It's not really arbitrary though, is it? It's decided by duly-elected representatives who answer to the citizens of the municipality. A government "of the people", etc.
I feel like what you're arguing against is precisely why we have local governments in the first place.
Congress could pass a law tomorrow, or California could pass a ballot measure with a 100% Yes vote, saying (for instance) that some random company now belongs to the government, or to Gavin Newsom personally, or to me, but the courts would still be obligated to strike it down since that grossly violates the Seventh Amendment. Ideas like this are commonly referred to as being checks against "mob rule" - the system recognizes that 'what the people want' isn't necessarily supreme when it runs up against other people's recognized rights.
