No, multiple of the core skill trees are flat out broken.

You can invest skill points in outpost building, only to eventually realize that they give you no way of even building flat ground.

You can invest skill points in stealth, only to eventually realize that the stealth mechanics are either utterly bugged out and broken, or if working as intended, were designed by a sadist who hates stealth games.

You can invest skill points in unarmed combat, only to very quickly realize that there is flat out no quick way of going unarmed.

And through these and several other broken skill tree paths, you can learn that there is never any way to respec and you're stuck having wasted skill points in cool sounding stuff that is actually useless. There are aspects of this game that are fundamentally broken.
