I don't know what gripe you have with the metric system, but people don't care about what the base units are based on, but that the relationship between the units make sense.
Also, the original definition of the metre did use exactly the distance from the north pole to the equator. It's just that the earth is not completely round, so you need to define this length along a meridian. The Paris meridian may be as good as any.
