Government never pays the owners what the property is worth. If you don't want to sell, the price is infinity.
That is such an old shibboleth, this idea that a thing is worth whatever its owner will part with it for.
So if we had a gold based currency, say 25 dollars/ounce of gold, and some dumbass wont sell his one ounce gold coin for an offer of a hundred dollars, then the value of that one ounce of gold would be 4 ounces of gold. 1 = 4? lolol
And suppose the person isnt so interested in money but only wants the cute young realtor asking to by his one acre of land to pay $1000 and go on a date with him, that price is $1000 and a date? How do you quantify the date?
Another time a guy agrees to sell his acre for $1000 and not having his legs broken. How does that price get written into the accounting ledger? $1000 and a not broken leg?
There does exist a range of reasonable price for items, and I dont care how many times pencil head dip shits like Friedman argues otherwise.
What a person is willing to accept in return for a property is a combination of sentiment, greed, a desire for fairness and also perceived value.
All Eminent Domain is obligated to pay is the market value.
