My whole family had covid, no one was sick or is dead
You are fortunate. Sadly, there are millions of people who cannot make that claim. Millions can tell you they have lost a father, or mother, or brother, or sister, or uncle, or aunt, or cousin, or nephew, or niece, or grandfather or grandmother, or even their own child. You are very fortunate.
Fortunately the rest of the world, which is mostly led by rational people (regarding the pandemic at least) are enforcing mitigation measure like stay-at-home, distancing, and masks. Billions of people are under such orders all over the world. And you are suggesting it is all for no good reason. Some would certainly doubt that assessment. Billions of them, actually.
The only logical reason for this is that the experts tell us that it is important to stamp out the virus ASAP. Experts look at the big picture, not what happened to their family and apply it to the rest of the world.
As a final note, America has around 4% of the global population but about 20% of the deaths. How does that make herd immunity look so appealing? Had there been a national plan in place, we would have had far fewer deaths, and in better control of the virus. Fortunate people like you find it easy to accept herd immunity. Those who have lost or are losing family members and friends do not, and will not accept it.
Fortunately, most of the people running things do not agree with herd immunity. Masks and social distancing where appropriate until a vaccine is available is mandatory in most places. This is not forever. It is until a viable vaccine is developed.
