We do not have an open frontier system, nor, truly, an opening frontier system, thanks to ever growing pursuits of political-cultural [no-energy!] pseudo-sciences and a massing of pseudo-scientists.
Maybe one of these days, enough leading scientists and political leaders both will learn money is nothing more than the token of energy (meaningful money in meaningful energies on the one hand and meaningless floods of meaningless paper, so to speak, on the other hand) and energy ties absolutely to a reality of open, or opening, energetic frontier system. War comes in two varieties, benign and malignant. Going for birthing an opening, an expanding, frontier system is a costly but most benign war, else the costliest wars there are, the malignant wars of an ever closing, ever shrinking in positive energies, entropic ugly, isolated island universe, deadly black hole-like frontier world system where the sciences, among too many other things, inbreed.
