True but it is a different legal system. London is used because everyone knows and likes the English legal system and the English courts. Scottish courts and the Scottish legal system aren't worse, just different. Wanting to do business with a contract using Scots law is a bit like trying to raise VC while incorporated in Maine. Nothing wrong with it, just not the way everyone is used to. The Scottish legal community has nothing like the density of commercial lawyers or the experience.
Not saying it wouldn't be doable for some businesses. If however your business relies on doing anything new/innovative in a legal sense then that is one reason why London is an attractive to be based. That is a big part of why "The City" is such a force, and legal services are a decent chunk of the UK's service exports.
It's true that there's a lot of advantages to English laws but we see a lot of companies using Scotland anyway for its Scottish Limited Partnerships which have a lot of tax/ownership advantages.
I'm sure there will be considerable debate and potential change to our commercial law if independence goes ahead. To my mind it's a huge commercial opportunity.
