Of course it's a free country. That doesn't mean there are no rules or that we can just make our own. If we want to drive a car, we need to pass a test and get a driver's license. If we want to practice medicine or law, we have to pass certification tests. There are rules (laws) about keeping wild animals, making excessive noise, littering. There are a great many things which are considered to be in the common good. This is how civilized societies work. The obligation to do some things together does not eliminate individual rights.

How does the re-distribution of wealth help civilization? It only helps to create a civilization of needy people.
