They're back, or haven't you noticed?
What you seem to advocate is the ability of a single individual to become a financial hold out and make unreasonable profit even to bankrupt a project, sort of like the EPA does now.
Wouldn't happen with a functioning options market, as I already explained.
I think Kelo was clearly wrong.
Constitutionally it was correct per the Tenth Amendment. As a matter of justice to the Kelo family it was a travesty. You can read more about that, particularly as regards selective incorporation here. The problem is that when any law is defined and enforced by the FedGov, there is only ONE way it is defined and enforced. With Federalism, we get to find out how better to manage the principle.
I can remember as a youngster we had 25 cycle electricity
Yup, you're a late-19th-early 20th Century guy all righty. Consider "go metric." You know who killed it? It wasn't Americans. When the world aircraft industry found out what the cost to THEM would be, the whole thing died. Once computerized equipment was available, it really didn't matter from a manufacturing perspective any more and the costs of conversion then outweighed the benefits. Consider too the differences between 22VAC 50Hz power and our 110VAC at 60Hz. These days the electronics can deal with either. Same with motors and variable frequency electronic drives. So this idea that universal standards are some kind of advantage is wildly oversold these days.
Come on you know why DC was impractical, Tesla killed that off early on.
I was born in 1938 in a very small town in Oklahoma, so I remember when we barely had electric lights at all in small towns and rural areas.
Metric made it to spark plug threads because they actually stayed in the cylinders. The public would never have voluntarily accept metric, still wouldn't in my opinion.
