And in nature you do not really have much big objects that could fall on you if you climb them.
Maybe a large boulder loose ... but they are very rare in my experience. So I guess it makes sense we are not prepared for it. What is much more likely, a loose rock which breakes off at climbing .. we are prepared for. Instinct reflexes are pretty fast in that case, I noticed ..
A cabinet being wobbly and starting to tip over towards you should feel pretty dangerous I'd imagine, we have various biological mechanisms that detect balance [1].
I would hope the ability to sense loss of balance equilibrium would innately result in having the strong urge to bail from that activity to sturdier ground, given you knew you could safely land on the ground without a worse outcome.
A tipping cabinet takes much longer to fall unlike a rock dislodging when you are climbing the side of a cliff in nature. Maybe it is simply a blind spot in our evolution like you suggest, evolution never optimized us for this edge case scenario not experienced in the wild.
