True at the time, but at the time Tezz didn't have the Planar Bridge.
And do you know how going to NewPhy with something that Valuable ends with?
Elesh Norn : "Oh interesting toy you have there, GITAXAS hack that arm off him and perfect it." Which of course would lead to the plot fairy having to come down, swing her crappy wand and bestow Jin with the exact solution to make it possible for Flesh to go through the portal, just like she did for Tezzeret finding the thing in the first place. Which is a thing that seriously needs to stop happening in every single block.
