Enjoy your case of beer and filthy cooking area. Unless you're some kind of environmental engineer, (which I highly doubt), you have no clue how certain chemicals will react, when exposed to high temperatures.
Seriously, what kind of "chemicals" are you suggesting people bring camping with them? As to "filthy", after being heated into the hundreds of degrees for an hour or two I'm willing to swab my fire pit and your cooking utensils and see which one makes the most colorful cultures.
I've been doing this over 50 years and you waited until now to tell me it's killing me... 
You can certainly do as you like. However, even commonly used plastics emit toxic fumes when exposed to flames-ask any fire fighter. Not to mention, cooking food over burned dirty diapers, dog poop, raccoon spit, etc. is very unappetizing.
