• A child balloon
  you inflate it, play with it for a while, then it explodes, you throw it away you inflate another one, maybe even a different color. the kid plays with it .. till it breaks, then you throw it away…

• An inflatable castle.
  you inflate it, play with it for a while, deflate it, move it around, inflate it again, if it has a hole in it, you patch the hole.

• The tyres on your kids bike,.
  You inflate it , kid rides on it, if it starts losing air, you fix it asap so you can continue using it.

in a way they are all equally valuable, but serve different purposes, different use cases.
