Expensive and difficult are different.

Care to show any credible studies that show this to be a problem?

Superconductive materials have 0 resistance which means there is no energy lost to heat.

As for how easy these temperatures are to hold, see your local hospital and ask them how easy it is for them to maintain their MRI machine's superconductive magnets.

What understanding the underlying properties of super conductive materials allows is for us to perhaps engineer some meta-materials that hold such properties at room temperature.

Actually, 138 K

They are the states that had laws on the books?

Do you know why private companies seem to always do things right from an economic sense? because those that don't do things right die off. Government can just do things wrong for a lot longer....that does not mean government WILL or does anything wrong and it certainly does not mean private industry does anything correctly.

Pluto does not fit the definition of a planet.

Government ownership of the road system is still a good idea but tolls should be used to collect maintenance revenue as it is the only way to accurately charge people for use and it balances with the need for maintenance.

Toll roads is absolutely a great idea. It does not need to be a privately owned road. With camera system based toll collection there is no need to have expensive toll plazas and you do not need to impede traffic to collect.

As someone in the middle class, I can tell you I do not get nearly the number of services I pay for.

they could pull an Apple and issue bonds in the EU to raise money that can be repatriated to the US without taxation and then repay those bonds in Euros held over seas.

My ring finger sits nicely on the side of the mouse. I have an LG gaming mouse though so maybe that is why it is comfortable.

That is the lamest excuse I have ever heard. I guess Adam Smith was wrong, competition is not good.

Why roll out fiber to the curb when 5G will deal with high speed internet.

You are an idiot that does not understand why Ma Bell was not innovative or what the court actually told the FCC when it over-turned the rules...you certainly do not understand the crap political game the ISPs have been playing with the FCC regarding when they do and do not want to be considered a common carrier.
