I'm not saying I think you're stupid, but I can only respond to the things you type. When you question the relevance of RMT and go down incorrect lines of reasoning searching for it, I feel compelled to step in and clarify.
macskull is arguing that the inflationary effect was lasting, not front-loaded, and they're using a downward trend in RMT prices as evidence of that. That's how it's relevant.
Now I don't find that argument particularly compelling, for reasons that are hopefully obvious, but I find your claim that accumulated wealth had no effect on the market thanks to inf caps equally weak. You yourself professed to having maybe a billion inf spread across a dozen characters, nowhere near the inf cap, yet somehow the cap prevented the effects of accumulated wealth? I'll buy that it curbed them, maybe even substantially, but of course long-time players having tens or hundreds of billions across their account would have affected the market. The only way it would have had no effect is if everyone was running at or near the inf cap at all times.
