For here in the US, or at least in the state where I am, it really depends on who is running the market. Some are as you noted here above with little to no regulation, and some require much more or everything from a business perspective.
For me, we live in such a litigious world these days - to the point where someone will sue you if they get soap in their eyes and it stung a little - to much more serious claims - it is just not worth not having insurance, nor the the proper due diligence to back up why you believe your product is safe - without just saying, "well, I studied and read everything I could so it must be safe" type thing. IF (and let's please hope and pray it never happens, but IF) I ever get sued, I want to have A.) the experience to know what I'm talking about, and B.) the proof to back that experience up...
Yep. There are a lot of sue-happy crazies out there (at least here in the US, for sure). I remember a gal over on another soaping forum who opened up a little brick & mortar soap shop recounting what could've turned into a very ugly situation had it not been for her preparedness with insurance, etc... One of the soaps she had stocked on the shelf for sale in her shop was a chocolate-scented soap. If I remember the story rightly, one day a guy and a gal came into her shop and were kinda loitering suspiciously around the chocolate soap when the gal just takes a bar of it right off the shelf and bites into it and dramatically claims she thought it was a brownie and broke her tooth on it, even though everything was clearly labeled as being soap, and she announces she is suing for injuries. Without batting an eye, the soaper goes into the back office and grabs insurance claim papers and brings them out for the gal to fill out. Well, I guess they weren't expecting that and they quickly made their exit out the shop without even so much as a glance at the papers, never to be seen or heard from again.
It's good to have all your bases covered.
