I bet all the "we should only charge so much then hammer everyone above it" are exactly the sorts who say we shouldn't need heating in the UK etc
I cant speak for others but I support it because energy (and water) are essential for survival and so I believe a base amount should be granted to every household to meet basic needs. It would be a very fair, considerate and kind social policy.
Think of it like a minimum standard of living threshold. Everyone gets this minimum standard i.e by receiving the same service for a fixed price. People who use more than this are free to do so and pay the market rate as they do now.
