TL;DR we can stretch a really long piece of fishing line from the Moon's surface to geostationary orbit. And we can probably send payloads to the moon by docking with said cable in geostationary orbit too. The funny thing is I literally mean fishing line here, they call for using a constant cross section cable made of zylon or dyneema with a diameter of about 0.35 mm. At least initially. Both dyneema and zylon with this about this diameter are sold as fishing line. Initial payload to/from moon seems a bit low as the line at the Moon end can only support 100 kg. The dynamics of such a thin, flexible cable which passes through an unstable(!!!) lagrange point should be interesting. We know that very long space tethers can behave in weird ways[0]. This idea is crazy and attractive enough that it warrants further investigation to at the least find out what the problems are so other people don't make the same mistake.
