If you are busting open ten systems a day, there is some logic to the control.

Things are always relative. Op was asking why refrigerants are so readily available if they are so "hazardous". R-134a can damage the environment but not, as far as we know today, nearly so much a the older refrigerants, R-12, etc. That "not nearly" explains why R-134a can be purchased at any auto parts store.
"Not nearly"..subject to change with little notice..
