Used games are not stealing. A game maker is only entitled to money from any given copy the first time it is sold, just like any other product. You wouldn't think of giving the maker of a piece of furniture some of the money you got from selling it at a yard sale, would you? Why should game makers be any different?

It's not illegal to copy something and personally use it either.

It's only illegal in regards to software, why is software any different?

If I can figure out the ingridents in coke, I can copy and make all the coke i want and coke can't do anything to stop me.

 The reason why it's illegal?

Software is easier to copy.

Why are used games bad?

Software is harder to damage.

Unless it's scratched, a New game is just as valuable as a used game.

While most used products have a decline in quality.

The "personal-use" thing is a drastic oversimplification, and isn't valid in all contexts. Generally, in fact, it is illegal to copy another person's physical product under patent, copyright, and trade-secret laws, with exceptions made in some very narrow cases collectively known as "fair use," but these exceptions do not cover all personal use, nor is it even a subset of personal use as some business cases are also covered.
