How do you suggest that musicians, song writers, designers and others make a living?
Because someone wanting a song hires them to write a song, or to sing. Like theatre actors play classical (IP free) pieces. Like an electrician is making a living by installing wires in houses, and doctors are making a living by curing people. And because they like it and do it for free.
By far most income of IP doesn't go to their inventors, but rather to people profiting from inventors in a hierarchical exploitation mechanism. Engineers inventing stuff in a company get a salary, that has nothing to do with the income that that company and their share holders will generate from owning that IP.
Why should people bother innovating?
Because someone pays them to find a solution to their problem they'd like to get solved. Once the solution is known, then we can move on to the next problem, instead of creating artificial scarcity.
There are two fundamental sources of "undeserved wealth". These are intellectual property, and owners of natural resources. When you look at the big fortunes in the world, they come from these two things, which are NOT related to production of wealth, but rather to an introduction of artificial scarcity. Natural resources are everybody's and so their value should go to everybody ; intellectual property is making something that is free of cost (sharing knowledge) into a scarce product. They are the levers of unlimited wealth transfers to their owners, unrelated to the production of further scarce goods and services.
