There's a difference between them though. It's rare that people max out their power when it comes to electricity. But with the broadband it's different. Any time you download a file you try to max out your connection. There is utility for an ISP to increase their bandwidth capabilities for customers. There's much less utility for electricity companies to be able to provide more maximum power to each home.
We also know from poorer countries that ISPs can provide better connections.
What "utility" do you think exists for the ISP to increase their bandwidth capabilities?
With an electricity utility, they may be able to turn on their coal generators to meet peak loads - it's a higher cost, but it's something they have available to use when needed. If engineered correctly, it also provides power consistently across all customers. Sure your house never uses enough to matter, but if all of a sudden an auto manufacturer wanted to turn on a whole new production line, they would have planned for that and gotten specific lines run to power it.
There is no equivalent for an ISP. Yes, they could guarantee that each customer gets x mbit/s and provision enough capacity (both to your house, to your neighborhood, to your central office, and finally to their peering connections) to cover all of that, but your internet would cost $300/m whether you use it or not and you'd be complaining about that too.

In the US? The fact that everybody doesn't hate their guts. A future government could easily screw them over in the future, because the voters don't like those companies.
In other countries? Competition. You offer a better service than other ISPs. This also gives everyone better internet and internet services can offer more things. Much poorer countries than the US and Germany have much better internet for a lower cost. As long as there's a big disparity there customers aren't going to be happy.
