The State could exist without Corporations,
but could Corporations exist without the State?

Certainly, the State could exist without Private Property
but Private Property could not exist without the State.

It is difficult to support an institution that protects
Corporations and Private Property for the following
example: Say you are part of a protest against
a Corporation's appalling environmental record,
and the protest is outside one of its sites.

The Police turn up when a few protesters brake
into the company offices and cause some damage.
They either beat up or arrest everyone and anyone
remotely concerned with the demo and keep those
in custody for a whole day.

You return home, only to find that your house has been
broken into. It could be argued that if the demo hadn't
gone ahead then there would have been enough Police
on the streets to prevent this from happening, except
for large demos they would bring officers from other
regions.

The argument which does follow, is that its easier
to protect a large target than to protect lots of small,
equally potential targets. It would also be cheaper,
not least because of the small chance the burglar
would be convicted, to put more money into job
creation and, most importantly, drug rehabilitaton
schemes.
