It's an interesting post, but I don't know if the problem is as bad as you might think. Of course, people sell intellectual property multiple times frequently. For example:

• If you're an author, you can write a book, and if you're good and lucky, you can sell it to a million people. Shoot, some popular authors write multiple books to a formula, so they basically write the same story with slight differences - and their readers like that.
• If you're a software developer, you might use the same or very similar functions and procedures in many different piece of software. Developers don't rewrite print functions or financial calculations over to make them unique.

I'm sure there are dozens of other examples. Of course, I understand it's not ethical to copy/pasta something you've been paid to develop by a client, but it's not so unethical to use an idea multiple times in different ways and on different platforms.

Anyway, thanks for this insightful post. I think Steemians should consider your points, but I'm just adding my .02 cents (in SBD, of course).
