I think we will just have to agree to disagree on that. I have to imagine residential houses still get built elsewhere in the world where they use the metric system. Recognize that 1/8th of an inch is already a fraction of the inch. If you want the same resolution in metric, just round everything to the nearest 2 or 3 mm.

In other words, metric is 2-3x more precise than is useful for the job at hand.

That's fine. I just prefer to use the best tools for the job.

Also, now that Imperial weights and measures are formally and legally defined (internationally) by their metric equivalent, Imperial system can be thought of as a layer 2 built on top of metric system, providing an suite of tools maximizing optionality.

It can be 2-3 times more precise, but it doesn’t have to be. You could just as easily say the imperial system is 8 times more precise because the 1/64th inch exists. You just chose 1/8th because that’s the amount of precision you wanted, but it could just as easily be 2 mm.

If you use a ruler and round all of your cuts to the nearest 1/8th inch, in practice that’s no different than using that same ruler and rounding all of your cuts to the nearest 2 mm.
