Covid is nasty, but at the end it's just another respiratory viral disease, a.k.a. "common cold".
It's just that before we ignored the human toll of the "common cold". (Yes, it is nasty and causes e.g. strokes and heart attacks and pneumonia. It's a leading cause of death that we never bothered to report before because we're so desentisized to it.)
This virus is worse than the common cold, by a lot. If treatment is available, it is not incredibly lethal. But treatment resources are finite, and the spread of the virus has been hard to stop.
Spread too much, resources run out and corona lethality spikes. Way before that, resources get diverted from other places, cancer treatments get delayed, nurse vacations get canceled (leading to burn out and hence less capacity in the long run).
Attitudes like this probably contribute a lot to corona spread being hard to reduce. People just ignore measures because "it's not that bad". Sure, your chances of dying if you ignore rules is probably low. But the larger consequences go beyond you.
Except it's literally not, it's a vascular disease.
