Inflation causes misallocation of resources. This is basic economics and is the reason Bitcoin is designed to eventually target a stable monetary base.
I don't know what "basic economics" you've been taught at the Bitcoin developer crashcourse, but as is, Bitcoin has been a highly deflationary currency, and at best, at some point in the future it will become mildly deflationary.
The whole thing is pretty much construed to protect against inflation. From an economic standpoint deflation is terrible. Most obviously it discourages investment (you're better off sitting on your money, and you're in a bind if you take out a loan since its real value will continually increase). Protecting against deflation is one of the key reasons why most countries manage their currencies.
This is not a problem intrinsic to cryptocurrency itself, and the folks who designed it must have known all that. So I think that either Bitcoin was designed with the aim of short-term profit goal of a pyramid-like scheme, or it was designed by some economic idealists who thought gold standard was too liberal in upholding the status quo of the moneyed class.
