>I think we ended up with private property because the alternatives have been tried and they are worse (e.g. tragedy of the commons) I don't thinl it is all or nothing. Private property is overall a very good idea and principle, and Piketty says that too. But when someone sees property it as inalienable right, at any level, is a problem. For example, if one person talks about a tax based on wealth, two people can hav…
I think that the idea of private property as an inalienable right is rooted in the enlightenment and on the same level as human rights. It is to protect individuals against spoliation by the state or powerful, and even to assert an even more basic right to own property at all. It obviously does not mean that property cannot be taken away from its owner but that this must follow a fair and lawful process.
It's actually a bit of a mess, conceptually and practically.
Property is really not a simple concept. Most people think of it as "Stuff I own" which reduces the argument to "I don't want the government stealing my house or my furniture," which sounds trivially obvious.
In fact all claims on property are complex - see also IP, stocks, and so on - and personal ownership is always a trade-off between individual benefits and socialised/externalised costs. This doesn't just apply to extreme situations like a war economy, or impounding the proceeds of crime - it's inherent in the practice itself.
You won't find much about that in orthodox economics.
