...I wonder if I may have become stupid, or if I just missed some context somewhere :/
They literally just said so:
Who? I thought I was replying to a top-level comment, and I don't see anything that says how we'd use eminent domain in that comment, in the OP, or in the article linked in the OP. Is it somewhere else?
Eminent domain,[a] also known as land acquisition,[b] compulsory purchase,[c] resumption,[d] compulsory acquisition,[e] or expropriation,[f] is the compulsory acquisition of private property for public use. Wikipedia - Eminent domain
I don't see the answer in this excerpt either, or in the Wikipedia page.
Given the tone of your response, I must have overlooked something glaringly obvious, but I'm just not seeing it 🤦🏻♂️
