That is the thing where our theories completely fall apart.
I really don't see *WHY* you should get 8-10k PEDs of oils and hides per day in the first place if there's not a market for them.
Instead of going for what (and in what quantity) the market needs, which I think is the smart way to play in 2.0, you're still playing like in 1.0 and just go blindly shooting whatever you feel like, how much you feel like then complain that you can't sell so much loot. Of course, you can't. But that's not something to blame on someone else, but just on yourself, since it was totally predictable.
You can always hunt something else (eventually mobs on other planets, which actually drop much lower oil percents), divert your hunts so you spread your loot in more stacks (the opposite of what we noobs have to do to stick with a single mob to make worthy enough stacks to list on AU), scale down on a lower level weapon and a lower level mob, scale down the time you're hunting to only produce as much loot that you can sell, etc. You have options! You just have to be willing to take advantage of them!
Do you think in real life things work differently? Do you think Apple couldn't make 10 or 100 times more iPhones if they would want? They sure could, but instead of doing so and end up with stocks they can't sell (sounds familiar?) they chose to only produce as many products that the market is actually demanding.
Disclaimer: Now, obviously, if you're not playing this game as an RCE, for profit, but instead you're playing it for fun and hunting at the top level is what's fun for you, then by all means necessarily continue to do that, just understand that since that's what you call entertainment, you have to pay (not be paid) for said entertainment.
