The idea that companies can corner entire markets has been proven false time and time again. Every "tech" unicorn has their valuation propped up by the idea they'll be the "primary gate holder" to some billion or trillion dollar industry. For Uber it was Taxis, for Tesla basically all ground transport, etc. None of them have been borne out and competitors are already well established. Blue Origin is already nipping at their heels with the recovery of Never Tell Me the Odds last year.
