I think people worry to much about these laws written by people that generally don't know the subjects they make laws about.
Can I advise anyone to break the law? No of course not.
What I will say though is
HOW WOULD THEY KNOW IF YOU HAD A SNAKE FOR 30 DAYS OR FOR 300 DAYS UNLESS YOU TOLD THEM?
So if you were going to catch snakes or other reptiles in Ohio on a regular basis should you pony up for a license? Of course 40 bucks commerical or 25 non commericial why not be safe and play by the rules.
Yet if I were in Ohio and found a single snake I wanted to keep and it was not threatened or endangered would I take it? Well, you make your own guess on the answer to that one.
Our nation is becomming one where every damn thing is illegal! Some places have laws that judge your "thoughts" and punish you more if your thoughts are worse then someone punished less for the same crime because their thoughts were not as vile. At some point people draw a line and to me telling me I can't pick up a common animal and make a captive of it is where I draw it!
At least Ohio is reasonable to a large degree. In Georgia it is "illegal" to own a corn snake including a captive bred morph. Still I know a lot of people that own corns in the Peach State and no one is rading their homes at least not yet.
Honestly the framers of our nation must spin in their graves that we fought for independance only to give up so much of our liberties to a tyrant we created for ourselves,
