You are granting Marx entirely too much credit in this one.
Rights are negative, not positive.
You have the right to assemble, but not the right to force others into your assembly.
Maybe more Ayn Rand will help you understand this key concept:
“Man’s Rights,” The Virtue of Selfishness, 97.
There is no such thing as “a right to a job”—there is only the right of free trade, that is: a man’s right to take a job if another man chooses to hire him. There is no “right to a home,” only the right of free trade: the right to build a home or to buy it. There are no “rights to a ‘fair’ wage or a ‘fair’ price” if no one chooses to pay it, to hire a man or to buy his product. There are no “rights of consumers” to milk, shoes, movies or champagne if no producers choose to manufacture such items (there is only the right to manufacture them oneself). There are no “rights” of special groups, there are no “rights of farmers, of workers, of businessmen, of employees, of employers, of the old, of the young, of the unborn.” There are only the Rights of Man—rights possessed by every individual man and by all men as individuals.
