The "drastic" price changes the OP speaks of probably means that those changes will cut into their profit margins. But at the same time, I don't think it's right for people to be selling low-lowmid level gear for 100k-200k each. These price changes are a decent way for Square to force crafters to sell gear at a reasonable price, since the "free market" isn't adjusting properly to the needs of a low level player.
With the reduction of gil rewards from leves and the inability to pump up the rewards to be profitable by turning in previous leves, players that level aren't going to be easily able to get the money to buy the gear if they remain at inflated prices. They would have to participate in the economy by gathering or crafting. Some people might say "too bad, deal with it", but I don't think players should be forced to go into gathering or crafting unless they want to. Some people just want to hit stuff, some people want to just craft, and some just want to gather.
