You own the physical integrity of your property. You do not own its value.
Crusoe owns a hut. Friday throws a rock through the wall.
→ Friday has changed Crusoe's hut. That is aggression.
Crusoe owns a hut. Friday builds a nicer hut next door, and nobody wants Crusoe's any more.
→ Crusoe's hut is exactly as it was. Nothing of his was touched.The distinction is Hans-Hermann Hoppe’s (A Theory of Socialism and Capitalism, 1989), and it decides more political arguments than any other single line in property theory.
Why Value Can’t Be Owned
Value isn’t a feature of the thing. It’s what other people are willing to give for it — a judgement in their heads, formed by their subjective preferences. Your house is worth what buyers will pay, your labour is worth what employers will pay, your painting is worth what collectors will pay. Each of those numbers is made of other people’s choices.
To own the value of your property, you would have to own those choices. You would need the power to forbid a buyer from preferring a cheaper house, an employer from preferring a better worker, a collector from preferring a different painter. That is ownership of other people — the opposite of Self-ownership.
And it can’t be made consistent. Every act of Production changes the value of something somebody else owns. The new bakery lowers the old bakery’s value. The better worker lowers the worse worker’s wage. If changing someone’s property value were aggression, every producer would need the permission of everyone who might lose by him, and nobody could act at all. A rule that forbids all action isn’t an ethic; it’s a contradiction (see Axiom of Action).
Physical integrity, by contrast, is objective and checkable. Either the rock went through the wall or it didn’t. Either the smoke crossed the fence or it didn’t. There’s a fact of the matter, which is what makes it something a law can protect.
What This Settles
The distinction sorts claims into two piles instantly:
| Physical invasion — aggression | Lost value — not aggression |
|---|---|
| Noise, smoke, or chemicals crossing a boundary | A competitor opening across the street |
| Fraud: taking property under false terms | A cheaper product making yours less saleable |
| Breaking a contract | An automated process lowering a wage |
| Theft, trespass, assault | A neighbour’s lawful building lowering your view’s price |
Everything in the left column has a remedy in Liability and Restitution. Everything in the right column is just the market — other people choosing — and the only way to “remedy” it is to stop them choosing, which is Aggression.
Where It Shows Up
Almost every call for protection from competition rests on smuggling the right column into the left:
- Protectionism: foreign goods lower the value of domestic factories, so tariffs.
- Licensing: new entrants lower incumbents’ prices, so permits.
- “Intellectual property”: copies lower the value of the original, so a monopoly on copying. No physical thing was taken — you still have your book.
- Zoning and “not in my backyard”: a neighbour’s lawful use lowers my house price, so a veto.
- Automation panics: machines lower the value of labour, so bans or robot taxes.
Each one claims a property right in the value of something — which means a property right in other people’s choices.
