I was always amazed they have this machine that can deconstruct and reconstruct any form of matter into data, even actually living and moving matter, to great distances at will and they have these weird problems in the episodes. Construction problems? Population problems? Food and water shortage? Need more dilithium crystlals? Need more transporter machines? Copy/paste the data and just beam the stuff to where you want it.
