Spectre/Meltdown Pits Transparency Against Liability

That's pretty much what the military and satellite operators buy. Older, simpler CPUs manufactured on larger nodes, radiation-hardened to boot and with years of proven track record and bug fixes.

And then they buy two or three per system for redundancy.

And they pay for that too. A RAD750 was about $200,000 each according to wikipedia.

I'd say that the hardening is the overwhelming motivator there. That's the reason to be on a huge node. If you're not worried about radiation, you could shrink the same design, making it cheaper and faster and have larger safety margins all at the same time.
