good point. though knowing what to do can make a big difference between a snapshot and a something frame worthy. many newbies start out with guns-a-blazing. but as you go on you start to define your own "rules" of what works and what doesn't... some just take a little bit longer than others
minor correction...

f16 rule is not a rule of composition... it's a standard that film and sensor manufacturers follow... but that's for another thread topic
Simple answer... because they can afford to. and because many clients just can't seem to get it out of their heads that better equipment means better photos. I know pro photographers who'd rather stick with gear that works but are forced to buy the "newer and better" just to appease their clients.
equipment DOES matter in the sense of 4 shot buffer, 3 second power up (my first dSLR was the Canon EOS 300D... try using that in a fast paced fashion show), lens quality, etc... but if it works use it! a friend and I just did a shoot this week for an international client and we were using a 18-55 kit lens for goodness sake
the BEST equipment is what you have in your hands right now... so go out there and shoot. once you've reached the limitations of what you have now THEN you'll be in a better position to decide what to buy to push those limits even further.
just my opinion... I could be wrong (CYA disclaimer
