Never gonna happen
As Ars Technica pointed out, who's going to pay for this fantasy? (Spoiler alert: no-one.)
The USSR tried to get to the moon by putting a very large number of engines in one booster: the N1. There's some spectacular footage of the consequent fireworks on YT; check it out. The more engines, the bigger the chance of one going bang, and though they claim to be able to survive an engine failure, I guarantee there are failure modes that lead to a very bad day.
When you're only incinerating three or four astronauts -- that's bad enough. Incinerate 100 billionaires and you've bought yourself a permanent place in the big book of human hubris.
Oh, and -- consider the mass of fuel this monster booster would have to carry (way more than SV.) How far away would you have to be at launch to be realistically safe in the event of a bad day? Again, YT has some horrific footage the Intelsat / Long March launch that rolled over to a trajectory parallel to the ground shortly after clearing the tower before crashing into a nearby town. The Chinese still haven't released casualty figures, but the footage of the aftermath shot by shocked western engineers on their way out of town makes it clear that hundreds was very optimistic. Doesn't the size of the energy release scale at something like the cube of the booster's mass?
Anyway, as the piece implies, there's more chance of me taking over as Bake Off presenter than this thing ever flying.
