All things are "the same" at some level of abstraction. But if you have to reach to a high level of abstraction to illustrate that the things are the same, I don't see that as a particularly insightful comparison. Sameness is a mundane observation at a high level of abstraction. Sort of like just tossing your hands up and saying "life sucks" regardless of what "system" you are living under and then concluding all "systems" are "two sides of the same coin".
