You're only taxed on capital gains. For it to be a six figure "loss" implies a minimum of $1M in gains alone. It really is ludicrous how entitled property owners act about their unearned windfalls.
Requiring data centers to be built underground would dramatically increase the cost. Imagine if we made the same requirement for roads, which are much louder and more dangerous!
On second thought, this negative externality thing really should be applied to roads, especially in cities. Guess I'm on board.
