Baddy killing doesn't count as a money source and it was never designed to be one.

Yes, they sometimes drop a green or blue gralat (and not often) but killing 1000 baddies would net you maybe 200~ gralats max (being generous) whereas 1000 bugs would be way way more because it's actually designed to be used as a money method Baddy killing is not.

There is also no "limited supply" baddy spawns are in large numbers and respawn very often, you could easily land 10,000 baddy kills a day if you did it all day.

The only reward you can count is the bounty daily which makes complete sense as you are defending the kingdom against baddies, this is the same reason it should be counted and a guild should be rewarded for defending the land if people to choose focus on baddy killing.

PvM and PvP are core concepts for any MMO I don't see how anyone could think removing the PvM aspect of an MMO makes sense.

Adding bug catching is just a bad idea it's a money making method and nothing more.
