As long as one is viewing humans solely as harmful disease vectors, obese people also take up substantial space in hospitals and cause further obesity through social contagion. However, we don't mandate that restaurants prohibit serving sugary drinks to those with BMI over 30. People with various STIs also do everything in your list, but that is addressed through awareness of safer practices, in some cases voluntary vaccination and PrEP, and research into better treatments, not through banning extramarital sex or shutting down locations where people meet for sexual activity. People who participate in injury-prone sports and activities also take up disproportionate hospital space, but the US passed the ACA in part to require medical coverage for people regardless of their lifestyle.
The reasoning for restricting behavior based on people's Covid risk (including vaccination status) is exactly the same as in the scenarios above.
People vaccinated against Covid can choose today to live a normal life, confident in the vaccine's protection against their serious illness or hospitalization, without scapegoating those not vaccinated for the entirely predictable seasonal and variant spread of Covid, or forcing struggling small businesses to hire bouncers to check the medical papers of every customer.
