What you're missing here is, the way you change all of your concerns, is to game alternative solutions at small size, and then test them. We literally could not cost effectively do so before. We can now. With weekly launches and vigorous testing, issues can be knocked down. Dev paths can be tried. Yet the perception I'm getting on this side of the screen is "we cannot do that, it's impossible to ever do that, don't even ever try" This is a recipe to halt all scientific progress. I don't think this is your intention, but that seems to be your argument. EG, you're arguing from "we can't do this because currently we don't know how to", so "oh well, that won't ever work".
