Only if that human is a 9th-level monk with the Unarmored Movement class ability that specifically allows that to happen. Without that, there's no way anyone is running up a bamboo shoot. And no, I wouldn't allow someone, even a 9th-level monk to stand atop a bamboo shoot. Because it specifically calls out that you have to be moving for it to work. You can't end your turn on water and still be dry at the start of your next turn. Likewise, you can't end your turn atop a bamboo shoot and still be there at the start of your next turn. And all that because a specific class has a specific ability that allows it. Not "just because it's too hard to deal with" the fantasy world otherwise, as is the case with the mythical climbing centaur. Make every centaur take 9 levels in monk. Problem solved.So here is where you and I are viewing the exact same thing, and with much of the same assumptions, but come to a totally different conclusion.
1. It is a physical fact (in our world) that a horse cannot climb a rope ladder because of the laws of physics.
2. It is a physical fact (in our world) that a human being cannot run up a bamboo shoot and perch atop it because of the laws of physics.
3. You and I both, as a GM, would allow a PC human to run up a bamboo shoot because D&D physics isn't real physics.
4. You and I, as GMs, disagree about allowing a PC centaur to climb a rope ladder because we don't agree on whether or not D&D physics would allow it.
It is TOTALLY WITHIN YOUR RIGHTS AS A GM to tell the centaur player that they are never going to be able to climb a ladder if that is how you feel that your game should run, but then allowing a human player to run vertically up a stalk of bamboo makes your centaur position hypocritical.
