Most Europeans have access to some kind of comprehensive public health offering, food that isn't killing us quite as quickly as American food does, etc. It is a system which requires thought and design that markets can't offer, since they're innately uncoordinated (the exception being oligarchies).
The idea that the market can be described as regular people deciding things is, by the way, fairly funny. We don't get to choose what gets made, and have to select from a buffet of often pretty poor options served up to us by people who are by and large not interested in anyone's wellbeing but their own.
Most of Europe recognises on some level that not everything that counts can be counted. That's the real difference. Regulation of new, high risk industries makes perfect sense from that perspective.
