Rocket flight would have to get a lot safer before that ever becomes a reality. Nobody is going to sign up for that if they have a 1 in 270 chance at rapid unscheduled disassembly. And even that rate hasn't been demonstrated to date - the risks for both Space X's rockets and NASA's space shuttle have so far been higher.

Yes. However it is possible in principle to make it that safe. Per current plans, Elon hopes to do that within a decade.

I hope it is a future that comes to pass. It would be amazing to buy a seat on a huge-ass rocket and take a trip to space and back. That's so far been only the realm of astronauts and billionaires.

if he can only avoid the boring boneheaded naysayers until then

Where are they gonna launch from, that I can get to in a reasonable amount of time from NYC, Chicago, LA, Hong Kong, London, etc? They can't build another runway at LHR, let alone a BFR launch pad.

Ocean barges. So you get on a boat, take a 20 minute ride, get on the rocket, and reverse.

No land purchase. No construction. A good radius from any buildings in case of accident.

London, Frankfurt, and Paris aren’t on the ocean. Three of the busiest airports in the world for business travelers.

They aren't, but a train to the ocean, then a rocket, is still massively faster than a transcontinental flight.
