And if you don't believe social constructs to be real, then I am confused as to why in your original comment "money" is given as something which is real. I think one could reasonably say that all social constructs are "imaginary" (whether that is useful is another question, but I would say it is not), but I find it more difficult once you engage in line-drawing within social constructs, especially so when you don't specifically articulate a boundary.
You are redefining the word "real". You know this. Some people get a delight from redefining words and seeing the reaction. It is rather tiresome; it doesn't help constructive debate. What have we accomplished here? Have you convinced anyone?
Feel free to disagree with a particular social norm or law and present your thinking.
If you want to get into epistemology, please do. But we have to find a shared language that makes sense.
