I mean, yes, those have been argued, but they're not exactly the mainstream view, which is that Alaska has paid for itself several times over.
Even if it is, Britain is wealthier (less in loan money) and it's possible (I'd argue probable) that Alaska gets incorporated into another unit of Canada (panhandle to BC, the rest as part of the NW territories at first), which would cut down upon on the administrative expenses.
And *Canada's tax breaks to and companies in the area will, at the very least, be different from the US's.
