If you have to ask, you will never understand.
And you had to ask.
It's a bit like "Thou shalt not steal".
But you might reply "Why ever [sic] not?" to that too, one suspects.
Where *is* this so-called "profit"?
And who caused it?
The notional increase in the value of my house has never done me any good. I cannot access that increase in tjhe form of folding mponey without doing something very silly, like selling (while I still need somewhere to live).
It is now just on thirty years since I was last in the housing market. Any increase in prices over that period has been caused by people other than me. I have not been bidding up prices. That's newer buyers and would-be buyers, that is.
<shrug>Making a so-called "argument" on the basis that you can't understand the human rights of citizens to their property is not the same thing as winning those arguments.
