A side-effect is the aura of spurious precision engendered by numbers containing several decimal places and these can be quite out of place in ordinary use. Traditional measures have a strong association with the culture in which they were established, and the right to determine and maintain them should be respected. They provide a cohesive force within their area of influence by providing agreement on the ways in which material things are described and organised. Even our legal system can be affected. With increasing complexity comes a declining understanding of the World and its attributes.
Most people now live in ignorance of the processes on which they have become completely dependent.
Metrication, with its effectively meaningless three-digit designations, does not conform to natural processes which proceed by twos, threes and fours. It is thus a further stage in our alienation from nature and reality. Common measures, like common laws, provide safeguards against loss of liberties of thought and action by technical trickery. There is no reason why they cannot be retained for ordinary purposes alongside whatever artificial arrangement is in vogue for abstract needs. All predictions of a regimented future assume complete decimal-metrication as a matter of course, complete with decimal time.
