What are some issues for teleporting?

Teleportation, while a popular concept in Science Fiction, raises several practical issues. One major concern is the preservation of the individual's molecular structure and consciousness during the transfer, as any disruption could lead to fatal consequences or loss of identity. Additionally, there are challenges related to the immense amount of data required to map and transmit an entire human body at the atomic level, not to mention potential ethical and security implications. Finally, the need for a teleportation infrastructure poses logistical and resource-related challenges.
