There will be restaurants and flights that only take the unvaxxed as their customers. Capitalism is awesome.
Logically speaking, no business will cater a "Unvaxxed Customers ONLY" as there is a huge gap between vaxxed to unvaxxed. If you do this, then there is a tendency that your business will be ruined not unless you overprice the products, or build your business in a unvaxxed concentrated location
The other side of that is, we will be starting all kinds of new businesses that will be for anti-vaxxers only. They don't want to get jabbed, but they also don't want to get contaminated by the vaxxed super-spreaders.
Anti-vaxxers are starting their own businesses and communities. It's just the beginning for them.
