Hey, if it only cost millions to install and maintain a leyline network with magic circles capable of transmitting matter for pennies then I would count that as teleportation, yeah.
To a point, although you can't make your own kiln for free. The tools in those trades consume a significant amount of resources, where computing is basically free once you pay for the hardware. Something like GCC is the software equivalent of a steel mill. Even if you could design one and give out the designs for free, you'd still have to pay for the raw materials to construct one.
