I’m 50/50 on this. On one hand, food deserts exist, and there are a lot of people who are struggling. OTOH, your comment makes it sound like you have a sharp cliff between “has 6 houses and personal chef + personal trainer on staff” and “can’t afford to eat 3 times every day”.
I could easily see either “reserved for billionaires and their playthings” or “available if your insurance covers it” with all the weird exceptions and “benefits cliffs” we’ve seen for the past 20+ years of insurance in the US.
That ignores other countries, but I don’t know enough to speculate on how e.g. Norway would handle a longevity vaccine.
