But electricity costs are not fixed, in the US at least, they float with the market. So electricity during the day is more expensive than electricity at night.

This is how a good market should work. Why should the internet be any different? I think the only reason why net neutrality is a thing people support is because of the monopolies the service providers have in many parts of the country. If there was healthy competition in the space, I don't think anyone would be talking about net neutrality.

As such, I think we should be focusing our efforts on deregulation and creating some real competition in the space instead of net neutrality.
