No, if Fetches were 2$ there would still be the same amount of them in supply (people would still open the same amount of boosters) and the price today would be the same (40-50). Was worth investing in when they were 10 a pop. If they were printed at Uncommon rarity, that would be a totally different story. (Goyf is an example of a card that was bulk rare when it came out, than was discovered broken and was 30, which was still a bargain compared to today's price).
Thing is as long as playerbase stays the same or increases, prices (I'm talking staples here) will rise or at least stay the same (or suffer minimal,bareable loss), EVEN if cards get reprinted, weirdly. Unless something gets a significant ban or a staple gets a superior version, but WoTC knows better, I hope.
