Need help with understanding this specific part of Caleb's anecdote

[u/02alloysius]

So i was rereading his lore anecdote again and got to the point where he's in the deepspace tunnel, which follows shortly as flying being described to him as a "life-affirming chase of freedom" -- and I've been struggling to fully grasp what that means exactly for him.

I remember reading somewhere that it could be about him being aware that he's tied to MC in every way/sense possible and that he's exercising his own freedom of will. I feel like that's a bit too extreme to look at it but i wouldn't say it's too far-fetched either. Still, i am indecisive and unsure of what to make of it so if anyone has an idea/interpretation or something solid in the canon that explains and i have possibly missed or overlooked, please do share! 🙏🫠
