Yeah I was being sarcastic. My point is that theres a limited technical challenges on the scale of feasibility ("anyone _can_ build...). The big challenges are on the cost/return side of things. Google Fiber faced tremendous pressure for if it was responsible spending or not, which they ultimately decided it was not. So there's good skepticism here about why the valuation would be that high, but I think its a stretch to say they don't have a moat and they're doomed / you cant build a successful company that way. AT&T / Verizon seem very comparable (they don't have a technology moat, they have a first-mover advantage which has been stable for a long time).
