I don't think the people who opposed those things look foolish even today. Most of those things, in their early days, were implemented haphazardly and with an incredible lack of regulatory oversight, and the reason they were not quite as disastrous as they could have been is that people opposed them.

And people opposing data centers today who are opposing unfettered data center creations will not look any *more* foolish than those who opposed the things you cite.
