Applying the mantra of open source to the underlying mathematics: Learn the mathematics of cryptography yourself to find the bugs within the mathematics. Don't place your trust in any person other than yourself. Especially don't worship some brand-name as a god who, as diviner-intercessor, is your sole information-provider on the subject.

In Texas, we are free to go buy any vehicle out-of-state (e.g., California) and import it into Texas via a Green Sheet and payment of the Use Tax (a.k.a. sales tax, but dodging the interstate commerce clause of the federal constitution). Once imported, the out-of-state vehicle can be sold at used-car lots, just like any other nonmilitary vehicle. Looks like a free-market to me.

No, this company probably budgeted that $20,000 for expenditure for purchasing 'X', whereas the accounting department would not permit reallocating 1) monies dedicated for purchasing 'X' into 2) an entirely different bucket of monies for donations to section-503 nonprofits. Here X is likely right-to-use software. Perhaps X might be hardware. Either way, acquisition of a durable good gets amortized over multiple years, whereas the entire donation to section-503 nonprofits hits the books immediately.

If humanity (or even only the G20) were to ‘throw everything they have at it to build a space station of the scale of Elysium in 150 years’ then we would absolutely assure that “Earth is beyond repair”. Although not strictly a zero-sum game, economics & engineering are relatively inelastic at each plateau of history unless some paradigms seriously shift, lurching humanity to the next plateau until the next set of paradigm shifts:
1) numerous liquid-fluoride thorium reactors (or analogue) at each locality providing abundant power for pennies on the dollar, when compared to current energy storage, distribution, and consumption technologies;
2) inexpensive extraction of minerals deep below Earth's crust (or analogue) providing more resources than the sum total of all of human history;
3) rail-guns (or analogue) inexpensively allowing vast mass per payload to reach escape velocity;
...)
infinity) and a bunch more paradigm shifts about which no person on the planet currently has the slightest inkling at all. Here the unit of measure of infinity is “bunches”—actually probably “bunches of bunches of bunches of ...” in depth & breadth.
