At $15 per gram of carbon nanotubes, and a minimum strand mass of 750 tons (earlier in this thread) is 750 million grams, or over 11 billion dollars for a single strand.

With the same money, you could refuel the BFR over 20,000 times, presumably putting 150 tons into orbit each time.
And what do you do then? Just stop supplying your space colonies and space stations, which we're assuming you're going to have by this point (given the purpose of the thread)? Whereas if you built the space elevator, and hopefully did a decent job of it, you can keep using it to send stuff up.
