By the time Europe could develop its own crew launcher, it would be past obsolete (just as Ariane 6 is). They should be focusing on getting around in space with their own vehicles, not getting there.
I’ve noticed that in public-policy areas in which we do a crap job of risk assessment/tradeoffs, it is areas in which there are policy agendas independent of the actual issues.
Other than a Windjammer Barefoot Cruise on a schooner in the late 90s (the ship went down in Hurricane Mitch a month afterward), I’ve never been on one, and have never felt a strong desire to do so. This tale doesn’t inspire me.
