Acknowledging the result of defeatism should push us toward a different mindset, not more defeatism. Over the long run, humanity has a pretty good record, carried by the people who refuse to give up.

Defeatism says otherwise!

Unfortunately when the struggle is against other people, especially the incumbent powers-that-be (in this case the capitalist overlords), those that refuse to give up have to fight long and hard to get enough other properly in the fight, and victory requires something drastic like at very least mass protests perhaps up to civil war level.
You were never at an airport. You fell asleep in your bed and woke up on the plane. Fighting the people taking you somewhere you don't want to go is definitely more work than falling out of the plane. It just has a specific advantage.
Not every airport is a huge commercial building with hundreds of people (also, you wouldn’t visit one of those to parachute jump). Some are akin to cozy shacks without a lot of traffic where you’re in and out in no time.
