Does government intervention in the market place guarantee decreased innovation?

For example-I recently bought a new cell phone. I only use them to make and receive calls, so I tend to use the same phone for years before I replace it. The last time I bought a phone, each phone had it’s own proprietary design for the charger input. That usually meant that for every phone I bought, I also had to buy a new chord to plug into the cigarette lighter if I wanted to charge on the go.

This, time, however, the salesman reminded me that various governments had established a standard, and now phones were going to use the same USB/input mechanism

That’s nice on the one hand. It means that I don’t have to buy new car chargers all the time.

On the other hand, it assures the fact that what ever is involved in designing this part of the phone, it will now cease to improve, at least not in the short term.

What is something else that is now mired in regulatory mud on the technical evolutionary path? Something else that will never improve because it seems convenient or popular to shackle it to a permanent standard?
