Apparently flamethrowers weren't enough. The next merchandise Elon Musk's Boring Company will sell are life-sized Lego bricks that you can use to build your own structures. The bricks are made of rock extracted during The Boring Company's drilling, and according to tweets from Musk, they interlock and have a "precise surface finish" so they could double as affordable housing materials. Initially, they'll be sold in kits to recreate versions of ancient Egyptian structures like pyramids and the Sphinx. It stands to reason that Musk could use these to build the Hyperloop infrastructure and stations, too.
