Because just because you put effort into it doesn't guarantee you can make a profit off of it, even if you intend to do so.
totally. its a logical fallacy that by putting work into something you therefore get something in return/own product of work... it could be that your work is just 'lost' and you gain nothing besides the value of the work itself. its up to the society to chose which is rewarded - if you put work in and don't obtain ownership, society should ensure that your work benefits all and not just a privileged few.
