Probably not, but we might be living in rickety homes, eating food that's mainly sawdust, and working eighty hours per week for almost no money. Some of us would still be slaves. A few of us would be fantastically wealthy and powerful, but even they would be limited by living in a violent world populated by uneducated and over-exploited masses incapable of doing things like getting an education and finding their own passions that lead to innovation, invention, and creativity.
The pleasant life you live today is due to government regulations. You know how you can shop at the grocery store without fearing that something you buy might literally kill you? You know the drugs you take for headaches? For whatever ailments you have? It's nice knowing there's some science behind those, right? Nice knowing they won't kill you, right? Speed limits? Are they a good idea? You might be more likely to think so if you had kids and wanted to feel safe allowing them to play outside. Flying to an awesome tech conference anytime soon? You'd probably prefer the plane didn't drop out of the sky, right?
Etc.
