The scarse resource is not that song or that movie. It's the time of the people that created that song and that movie. That's is part of the cost of production.
This is similar to there are millions of houses but only a few in the most scenic places. Want one of them, pay more. It could be the same for the most popular songs and movies. The time of their creators is more valuable than mine. When writing software probably the other way around.
Of course they don't sell songs and movies like that and creators sometimes only get peanuts. I'm not a very good Devil's advocate.

That's not really valid, though. Time is not the thing being exchanged -- it's impossible to do that -- so isn't a resource, scarce or otherwise, in the sense we mean. On top of that, the previous commenter made an error -- property rights aren't a solution to disputes over scarce resources, they're a solution to disputes over rival resources, regardless of how scarce they are. Since time is not transferable, it's not rival.
More to your point, though, the consumption of time engaged in a productive activity is a capital expenditure, with the risk borne by those expending it, as with any other capital expenditure -- your investment lets you bring a product to market, but no one is obligated to do business with you, and whether people compensate you enough to generate a sufficient return is up to them.
We do not "trade" time in jail between society and an individual. We deny certain freedoms for a period of time. There is no economic equivalent when it comes to time.
Learning is a process that consumes time now for improved capability or efficiency in the future.
