I thought the same thing about 3 until I realized that I’m more than 7 inches tall/wide/deep, so I can’t actually pass through anything, just get horribly mangled when I make it halfway through the door.

Now here’s the million dollar question: how many times per second can I teleport? Because if I can teleport at let’s say 1khz… now we’re talking

I don’t personally understand the desire to do this beyond “it’s the principle damnit” or doing illegal stuff but if you really want your phone to not be tracked then just use a verified faraday bag. Or make one yourself if you’re poor and then validate it yourself.
