"festering hatred of the English" For there to be a continued festering hatred there would need to be an existing one! There isn't. Not for the vast bulk of Scots anyway. There are exceptions of course....every country has its bigots.

As to the currency union obviously it would assist trade but yes, would still have a big downside. The current supposed housing bubble with talk of rising rates and the drawing back of Help To Buy is an example of what would remain post independence within a sterling zone. Outside small enclaves there is no housing bubble in Scotland. As is so with much of England too.
