At the field I fly at you are required to have insurance. The people who always follow rules just do. The people who do not follow rules will not.
In Illinois where I live. To register, own, purchase, license a car proof of insurance is required. All car insurance clearly states only licensed drivers are valid. (I bow to the point the car could be towed off the lot to where you store it as a collector but believe me this is not the case this ad is making)
This is a similar case.
These rules are designed to force compliance with the laws, but, those who do not normally care about legal compliance will not follow them.
