> Arguing against it when that's how it's being used is, in my opinion, essentially arguing against the very concept of eminent domain

You're giving a blank check to use it as long as it's infrastructure, and as any simple rule, it's prone to get abused way beyond it's primary goal. IMHO the issue is nuance and balance, we should accept that whether it's applicable is an "it depends" matter.

Keeping it too simple and black and white means companies can now strategically place data centers and get the local government to seize all the land leading to it, and vice versa, local govs can nudge companies to target specific places to seize wherever they want. Especially as the plans aren't required to come to fruition.
