I suspect that it is impossible to prove than an organization actually 
needs a larger block than they're requesting. This isn't like the fire 
code, where there's a minimum square footage per employee, after all.

Agree, and you also missed "creates a risk that the buyer will purchase 
the biggest block they can find, but then the next day the amount of 
space they *actually* needed comes on the market and they're locked out 
of getting it"
