The idea isn't that stupid. You just need to be more than 2 people. Is there any reason why a group of self-employed people can't go together and get insurance

The idea isn't that stupid. You just need to be more than 2 people. Is there any reason why a group of self-employed people can't go together and get insurance as a group? If the group is relatively homogenous and are able to pay the bills, surely the insurance companies would be interested?
