The thing that annoys me about all of this is that I see this in almost every MMO game I play. The people who don't want to (don't have the time to) farm call it an "exploit" and ask for the bar to be lowered to their level of casual gameplay 2-3hrs a day, and everyone else suffers because of it.
Humans are creatures of habit. We will always seek out the most time efficient way of achieving things. This is getting nerfed just as Trade/Explo/Exo data got nerfed, and next on the chopping block will be Stronghold Carriers until the only way to get PP merits is the "intended" way. Very slowly and taking months to unlock PP modules, to which you will all be back here on the forums complaining that it takes too long and stop engaging in PP entirely.
Rare goods are already restricted by the time gating of the commodity respawn at stations and the limited quantities you can buy. "BUT WAIT" I hear you cry "FLEET CARRIER OWNERS CAN SELL THOUSANDS AT A TIME", but this takes DAYS of grinding to fill up a carrier, and lets be honest if you're more than 500 hours into this game and don't have a FC by now you'll probably never buy one, so what does it matter? What difference does it make if you spend a week doing your chosen gameplay loop and having fun scanning planets and mapping exobiology signals for a reward, and someone else wants to sit AFK in a station for 10 mins to buy 25 items and fly the 2min round trip to their FC and back? They are arbitrary rewards that have no impact on your gameplay as all the PP module rewards (with the exception of pris shields and MAYBE the mining lance) only affect combat, and if you don't play in open or engage in PVP you'll never even need them, so why make a big deal about this?
Let people play the game. If they want to grind and you don't, then don't grind. This game is nothing but a grind and it takes nothing of value away from you if you spent 3 weeks getting something while enjoying the game that someone else did in four days.
