The FDA made it mandatory for food manufacturers to list their ingredients on food they sell. Prior to these laws no food manufacturer was willing to do this freely, for fear of someone else stealing their recipe. But now consumers can make informed decisions and avoid foods that will give them severe, life threatening allergic reactions.

Every citizen who drives a motor vehicle must be issued a driver's licence by the state they reside in. This enables a minimum understanding of how a complex machine (the highway transportation system) works so that other drivers / participants of that system can use it safely. Without regulation, vehicle collisions would be rampant and the system would be far less stable.

Not all government regulation and oversight is bad.

I highly recommend reading the book "Click here to kill everybody" by Bruce Schneier [1]. Bruce has been in the cyber-security world for a long time now and is considered one of the world's foremost experts on cryptography and computer security. In this book he makes projections about the "internet of things (internet+)" and the security problems that will come with it. He strongly advocates for government oversight and legal reform in multiple areas.
