It all comes down to one thing, the Frogs are too proud to admit that for them to be successful they must be ruled over by…Corsicans.

potential ports would only be useful if you have the industrial capacity to convert them to actual ports. heck, if you’ve got the industrial capacity, you can make a port where there wasn’t previously any “potential”. the Romans, Greeks and other ancient civs were doing this, creating protected ports where previously there was nothing but shallow coast open to the sea and storms.

L = total surface area of land;

ARABLE land. the Sahara is larger than continental US, and almost utterly useless. perhaps you consider this to be incorporated in your potable water clause? extensive mountain ranges such as the Hindu Kush or large marsh/delta complexes or the forested wastes of Siberia would also be disqualified for most purposes.

further i would say that “reserve industrial capacity” is of utmost importance. a by-product of a large and intra-competitive industrial base is that you might have many, many manufacturing companies operating at “full capacity” ( 40 hours / week and 50-52 weeks per year ) but that this still implies a large “reserve capacity” which can be engaged in times of opportunity or emergency ( say, war ) with only minimal or nominal increases in input and maintenance + staffing/training necessary to turn it up to a 24/7/365 production house, which can quadruple standard “full capacity” output.

i would add that this last point is the major failure of the post-WW2 financialization / de-industrialization which has taken place across the Marx-advocated International Free Trade West.
