Additionally, base 12, would not act like 12 does in base 10, thus if base 12 is your key point of reference, a foot should be 10 in base 12 for inches..... I honestly cannot make any sense of this part of your argument. The symbols 10 would only look like ten they would still mean a dozen and the properties would remain the same. Furthermore people don’t think in twelves because we are not taught in a dozenal numbering system. And there is no need for twelve fingers it would be a simple thing to create two additional hand symbols to teach children to count to a dozen. Twelve is a great base. I would prefer it but it isn’t the sort of thing that can be changed.
