Why the high cost of moving? 30% of old plot mimimum price is not fair

[Rasikko]

Say someone is moving a large to another large now that they have more freedom to pick the location they like. Is there a reason why they have to pay 43 million on top of the near 50 million originally? (or in the case of 5th class, 34 M more)

I mean it is not even fair when you are comparing the price of moving across classes, just.. why?

SE can't math, or am I missing something here..?

50m - (50m * 0.30) = 35m
