    I agree with your choices but your logic for the teleportation doesn’t hold up. You’ve assumed your momentum wouldn’t be conserved through the teleportation in a weird way. Assuming momentum is conserved, you would still fall just as quickly. In fact, you would reach terminal velocity in short order, and would have to continually teleport to keep yourself from crashing into the ground. By itself that would be bad enough, but you moving through the air between teleports would cause the air to move as well, so assuming you could keep up and hold your elevation, your velocity relative to the ground would increase to some number higher than terminal velocity. Think Chell continually falling through portals. Now you’re stuck unless you can also teleport slightly to the side without falling. Best case you go to one of those indoor skydiving places and get in so you can slow down without dying. I was going to explore what would happen if your momentum somehow wasn’t conserved, but that would imply some absolute fixed frame of reference or magical mumbo jumbo, neither of which exist.

    You could totally travel faster though, without even needing to walk. You would also be super dangerous in one on one combat sports. A well placed 7 inch teleportation can easily get the win in the right sports.

      I disagree with your teleportation assessment. Just as I don’t think my momentum would be conserved, you think it is. You have no more reason to believe it would than I have to believe it wouldn’t. Because there’s no foundation for teleportation as it doesn’t exist.

      I’m not sure what logic you want to use with something that is made up. But im gonna go ahead and assume my teleportation will work on my rules since no rules were ever specified.

      You can feel free to use whatever made up rules you want for your own magical power.

        Conservation of momentum is a law of nature, making it natural to assume it would still hold even with a hypothetical power. But you do you. It’s ok to be wrong sometimes.

          conservation of momentum is only a true, when translational invariance holds. In addition, there may be a countless number of mechanisms by which teleportation changes a persons momentum. E.g. maybe the way this kind of teleportation works is Star Tek-like and your atoms get disassembled and reassembled, meaning they don’t need to have the same overall momentum, when whatever is doing the dissassembly stops atoms for dissassembly.

          But what if teleportation doesn’t move you from A to B, but just lets you disappear and reappear while you’re just standing there, so that there’s no momentum at all?

            No momentum at all relative to what? Relativity tells us that there is no fixed frame of reference. In practice what that means is there is no universal zero velocity. You only have velocity relative to other things. The implicit assumption in your argument is that you would have no momentum relative to the earth, which in itself is problematic. After all, the earth spins at a rate of 360 degrees per day, so not moving relative to the earth would mean moving 463.83 m/s relative to the surface of the earth at the equator, which is supersonic. But maybe you mean relative to the surface of the earth. What if you go to the moon? Or mars? Or into orbit? Maybe you mean relative to the nearest big thing. If you could somehow teleport from the ground into a plane, would the plane count as the nearest big thing? What about a bus? That’s on the ground, so maybe the nearest big thing would be the ground, if the mass of the thing matters in how the nearest big thing is determined. You can see how this can quickly turn into a mess of rules and special cases.
