The system before was too op with people being able to collect crops and expand while getting paid extremely well via the farmer job.
While I don't like not getting money for the massive amounts of farming I do, you are meant to farm and sell your items (if you are doing this at the warp meep set up you are ignorant) and I still make 25k in 20 Minutes and can go do other stuff while it regrows.
The point is not to devalue the farm products since a lot would be abused via villagers and the job economy if we used the old way. Now people have the choice to sell their product or expand and not get both. It isn't hard to sell your farm product, learn how to up arrow to your advertisement and annoy the crap out of /te with a have decent deal.
