Would you still “Jump”?

Jumping; I came across this concept when I watched the movie called “Jumper”. In simpler words, jumping has always been known as teleporting, a really remarkable ability to have. Teleportation is defined in Wikipedia as:

“Teleportation is the movement of objects from one place to another, more or less instantaneously, without traveling through space.”

What if we could actually teleport? What if we can be in one place one second and another place in the other? But what if this ability comes with a price that makes this ability almost useless? Would we still use this power if it came with any of the following back draws?:

1. You can jump(teleport), but only to a place in between a crowd of people and your clothes have to stay behind.
2. You can jump, but everytime you do, your penis grows 2 centimeters shorter.
3. You can jump, but only along with transformation into another form; be it an animal or be it a pile of dung.
4. You can jump, but with the loss of voluntary control over yourself for the next five minutes which probably would lead to incontinence of urine and feces.
5. You can jump, but first you have to find someone else with the same ability who is willing to exchange places with you.
6. You can jump, but everytime you do, you age 5 years.
7. You can jump, but first you have to count from 1 to 100,000 in one go.
8. You can jump, but with the price of an exponential increase in your body hair.
9. You can jump, but you have the choice of either a raft at sea, the north pole or an underground coal mine.
10. You can jump, but you cannot come back.
