Two things:

  1) Because of "everyone else has it, we must also be able to get it" 
mentality.  Else they'll threaten with suing based on restraint on 
trade and other ludicurous reasons.  A precedent on creating swamps 
sets pressure to continue to make the swamp even "swampier" (e.g., by 
relaxing allocation rules even more, not even trying to get the act 
together, etc.)

  2) 35K unique sites could result in a lot of dynamicity in the 
routing tables.  I wonder if you have seen BGP Update report? [1] 
Multiply 35K by, for example, 500 or 1,000 updates per day, and you've 
got quite a bit of churn at your hands -- churn that you can do 
nothing about because folks at DFZ believe they have the right to do 
anything they want with their advertisements.
