There are some natural monopolies for which there is a strong argument
for nationalisation. They are few, basically just major infrastructure
provision. Railtrack, OpenWorld, Transco, National Grid. That sort of
outfit. I don't see any great natural monopoly in train/electricity etc
provision using that infrastructure.

When anything has to share bits owned by someone else, there are
inevitably going to be problems.

Different train companies using the same track and infrastructure, which
they don't control.

ISPs using the BT phone lines, etc.

Buses competing on the same routes.

Because of this they need regulating.

No they don’t with buses competing on the same routes.

Not quite sure how regulating lots
of different companies is easier than one.

It isn't, but you do get the advantages that come with competition.
