This is, of course, currently about covid-19, but I think that the political arguments mostly apply to infectious diseases in general. ..once they gain a certain significance.
I don't doubt your perception though. The discourse might vary greatly between countries, languages, etc.
Social distancing restricts some, but even without any legal enforcement I wouldn't be surprised if people just don't want to be close to others like before anymore. And for perfectly acceptable reasons!
There's a variety of relatively low cost preventable steps that would just help in general if people followed them (may or may not fit your definition of social distancing).
I'm thinking of stuff like
- Contactless payments
- Head nods instead of handshakes for greetings
- More remote work options (where applicable).
- Mask wearing on public transit or by people with lots of personal contact
