the Scottish independence vote.

When Scotland becomes independent the Scots can
act independent from England but if they want they
can join England in single questions.
Scotland would have the freedom to decide on many
more questions which they don't have
when they remain together with England.

The Scots have the chance to ban GMO food, with
staying together with England they probably don't have
 this choice.
The Scots have the choice to introduce organic
farming as the main form of agriculture,
which brings about the highest quality food.
By staying together with England they probably don't have
this choice.
The Scots have the chance to say no to aggression
against Russia. By staying together with England
they probably don't have this chance.
The Scots have the choice to go ahead to overcome
Psychiatry which is constant fraud towards those with severe
mental problems.
By staying with England you probably won't have this
chance.
You have the chance to question the current
democracy and decide on ideas to try for improvements.
By staying with England you won't have this chance.
and so on and so on.

In all this questions the British political establishment
will highly probable not or not really support named
intentions.
When Scotland is independent they have these and
many other choices they simply don't have when they
stay together with England.
