If we write off the US what does that do to our standard of living?

Assuming pipelines are obviously orders of magnitude more efficient than shipping by tanker. It also then still requires a pipeline to the east coast as a first step, which we cant get built due to Quebec, who ironically import all their energy from the US. All these costs and we then have to compete with countries on that continent who can build pipelines to Europe.

Given our small population we are the 4th largest exporter of oil and our loonie essentially tracks oil prices, hence it makes up such a large component of our standard of living. This idea we can pivot seems silly at first glance, but I'd like a differing opinions if one exists.
