While the idea is great I'm not convinced that the Soviet Union is the best example to demonstrate the concept. Yes they had a "right for leisure", unless the State decided that you were a slave and sent you in Siberia to knock hard rocks for the rest of your life. Or your "rest days" were in fact forced, unpaid labor (subbotnik), no different than their previous feudal serf system.
Same for a "right to a house", where the State provided you with a filthy, overcrowded slum and call it a day.

I am sure Soviet Union is THE BEST example to demonstrate the concept.
It shows perfectly that you can have anything, anywhere and as much as you want - but it won't mean anything if you take away people's economic freedom.
It depends if you discuss about practical things - right for housing or things that are more abstract - right for privacy from the government's prying eyes, banking secrecy or in the US, freedom of speech. In the later case, I don't think that it affects the economic life.
