That's not really the right thing, though. Which is borne out by the end of the movie. Nothing about Indiana Jones' character suggests he'd be fine with taking a bazooka to an artifact that important/valuable, either. That'd be absolutely the WRONG thing for Indiana Jones to do. Which is why he can't do it.
But this is a weird nitpick guaranteed to derail the thread down a rabbit hole of letters-to-the-editor Wizard Magazine theoryfighting, so let's not get into that if we don't have to.
I always hate when someone continues the argument but then says lets not continue the argument. If you weren't interested in derailing then why did you offer a rebuttal?
The reason it works out by the way was in the second part of my post you cut out. Literally God Almighty has to descend from Heaven to clean up Indy's mess.
The conflict he has on that cliff top is between saving the world from a terror the likes of which it has never known and his own selfish archaeological curiosity, which he ultimately surrenders to. I mean, that is literally what Belloq is saying during this scene. "we're not so different you and I Dr Jones" and Indy proves it by dropping that bazooka.
Indy pulls through though, because in the end of course he's different to Belloq. He has faith
and humility and thus he is rewarded by God. Belloq in turn is undone by his own hubris, appearing before God in the dress and with the rituals of God's chosen people, as if God could be tricked by a bunch of Nazis.
God saves the world at the end of Raiders of the Lost Ark. That is literally what happens at the end of the movie. Then he gets locked up in a warehouse. I'll admit that last part is a little bit confusing theologically.
Contrast it to GotG where Starlord saves the world because he's SpaceJesus. It's not really the same at all. At least not from Indy's perspective. Maybe from the Ark's.
Now that I've had my say let's stop talking about this.
