Well, being the graphical genius you are, you should be able to understand that not everyone has the ability to create brushes. That's why people who aren't selfish create sets for other people to use.
At least I can manage to scratch a living off of my profession, do you get paid to be a raving pokemon fan? Sounds like an exciting job. People who don't have the ability to create brushes needn't make brushes at all. Despite popular belief, "Axel," mindlessly brushing around with downloaded grunge sets is not the only thing you can do with programs like Photoshop or even (need I even mention it?) Paint Shop Pro. And programs like the GIMP don't even feature such a function, but also lack other vital operations. I'd prefer you do all your work in Microsoft Paint than you use downloaded photoshop brushes. Someone with access to more than brushes shouldn't be so condescending as to only work in the field of brushes and colour balance.
And the quotation marks around Axel were placed there because I don't know who you are.
