If I go to my Planar Quill and spend 1,000 planar mana of each color and 12k gold to boost the world enchantment I can sell it for only 12k gold at consignment. That is a loss of 5,000 planar mana IF I GET THE TOP TIER WORLD ENCHANTMENT.

will, tbf, the norm for selling things is you get less back than you spent, but... I doubt actually using the world enchantment would earn back enough rewards to make the investment worthwhile, so what's the point?
Planar mana will ultimately become nearly valueless (once you finish your personal realm), so there's little opportunity cost to blowing it this way.
