world wide web

It's the big problem of the net: how do you make money if everyone can access the files you produce for free?

Earning money is not evil, it makes it possible to produce more art or information. It's a waste of talent to need a day job to support what you consider your real work.

In the old world it was simpler (but not easy): make a deal with a publisher, they will pay you for the privilege of printing (or publishing in some other way) your works, and their customers (perhaps with a bookshop or something in between) will pay them to get access to your works. Copyright ensured that publishers would have to make a deal with you, they couldn't just take your work as published by another publisher and copy it.
