We can learn a lot about freedom by understanding how Marx wanted to establish communism. One of his ten planks of establishing communism was this:

"1. Abolition of property in land and application of all rents of land to public purposes..."

Take away property and you take away freedom. If a man or woman cannot own land, a house, his or her own things, freedom is gone.

Note that there is more than one way to abolish property and ownership. One is to make it illegal, to not allow ownership. This is extreme, of course.
