The main reason for the continuous increase is people getting richer. Compare it to xp...look at how hundreds of people now have 5.4b xp. That would have been insane a few years ago. But people keep playing, 10-15 years in, and their xp increases. Same with gp. People make more and more money, and so they can afford more and more expensive rares.
Rares give people something to do with their gp. I've heard people say Jagex should release rares, but that would mean gp would be lying around waiting to be used elsewhere. Inflation of gp/xp/items/etc will always continue. The only real way to fix it is reset the game, but that of course would be dumb.
