I thought about that earlier nep, and honestly, I can't speak for anyone else, but if that's how England felt then I'd say go for it!
The debacle surrounding the Scottish Pound is only because iScotland has been threatened with having the Pound taken us off us for leaving the UK. I don't see what's wrong with a currency union. I don't really care what we use, when Britain first joined the EU, for example, I really wanted the Euro. Would make travelling in Europe so much easier.
If Holyrood and Westminster had swapped places (e.g. the UK PM and government were based in Holyrood and vice versa), and what you describe was true, then yes! Independence would be the way to go!
The last part makes me think you've seen a Yes campaign calling those south of the Border "idiots". That's not cool, which campaign was it?
If Scotland remains part of the UK, and say Wales had a referendum citing similar reasons, I wouldn't bother. People have the right to choose how they're governed, and if enough people in one country feel the Union isn't working for them, then a fair vote will decide how best to proceed.
