Half of what you wrote is either unrealistic or completely unrealistic.
1) fully multi-reusable rocket - not yet proven. It can happen, or can't. No need to imagine anything - Shuttle famously had been marketed and designed as super rapidly and fully reusable. We all know how it really went.
2a) food costs - negligible savings.
2b) inability to eat tasty or even gourmet food, in a normal human position and environment (jet or first class seat) is actually a negative factor. But let's disregard it.
3) passengers in pods ??? - what's a "pod" here? A space suit with a different brand name?
4) passengers without space suit - lolno, won't happen. Maybe it would be some fancy low profile suits, like new SpaceX ones for Dragon use only, without space walks and EVA capabilities. Even then they would still be pressurized airtight suits. This is actually yet another negative factor for my list above. Manufacturing thousands of unused space suits in different sizes, so that on any flight they would have a hundred suits in arbitrary random sizes ready at each start complex is a laughable idea. Just the suits cost 0.5 million dollars each (4 suits = 1 fantasy Starship launch price (fantasy price, not the ship, obviously)). And their maintenance is also not cheap, regular checks, repairs, replacements, cleaning, etc. Costs would be astronomical.
5) little to no staff - doubtful but maybe. 2 pilots would be needed at minimum, and I suspect one or two more aux flight engineers too. No service crew, yes, that would be cost savings. But lets look wider. Maintenance crews for the Starhip - much bigger and much more senior and technical. Dispatchers at the cosmodromes - a lot of people in every location, dozens of people per location. Aircraft can be controlled by a lone dispatcher, maybe with an assistant. And the list goes on. There will be much more people involved per 100 passengers than with any aircraft of any size.
6) 10 flights a day - funnily enough, some industries DO NOT benefit from economies of scale. Like almost at all. Starship is one of them. Regardless of the number of flights per time period, if you will increase number of rockets, their costs would almost wont go down. They will stabilize after first few units and stay constant. Same with all operational costs. If you need to fuel 1 Starship you pay X money. For 10 Starships you pay 10X and no less. If you service 1 flight you pay in aggregate Y human/hours of highly qualified workforce wages. If you service 10 flights, you will pay 10Y for human/hours.
The only scalable component here is engine production, but after stabilizing manufacturing at some large number per year, cost drop would also stop.
And finally - 10 passengers per flight is not 20k, it is 200k dollars, which is 2-3 times more than entire top model large business jet rental for the whole flight. And jet is available on demand at the time and destination which YOU decide, airport is conveniently located almost in the city border and there are literally no restrictions of any kind in such flight for rich people. E2E rockets are not viable.
