If I was the Michigan governor I would say protest away.
But....if you get the virus you are last in line, very last for treatment, and if you give it to some one who was not protesting, you go to prison.
"if you get a virus"
That presumes you didn't have a virus before you get out. Why would anyone healthy be in quarantine?
This virus spreads through close contact, the more people you have close contact with the greater the odds you will get it and the more people who do such exponentially increase the infection rates.
Lock downs and social distancing keeps the infection rates down so that the health system can prepare and so that there is more time to actually research and understand the nature of the virus. For instance we still do not know if infection confers long term immunity.
Those countries that did lock downs quickly and rationally, such as Australia, have much lower infection and death rates than countries like the US who had a delayed and chaotic response.
If is not total lock down, it can't work. Reason for it is that people are still going to get a food, and may get infected in stores, whose workers could be carriers. Therefore, you didn't do anything.
Second, who delayed lock downs in the US?
Our lock down in Australia still allows travel for food, exercise and social distancing in public, yet our infection and death rates are some of the lowest in the world, the point is it has to have national consistency and leadership combined with a rationally funded health care system and social safety net.
In Australia there is none of the economic desperation there is in the US let alone the infection rates.
Trump was all over the place even after it became clear it was a global pandemic, resisting calls for lock downs, initially calling it just a flu, telling the American people there was nothing to worry about. Unlike Australia, where the governors met with the Prime Minister in a national cabinet and came up with coordinated and early responses, the states in the US were all over the place with differentiating measures and the President seemed totally delusional in the early weeks of infection spread. (Even now he is with disinfectant remarks and encouraging dangerous protest gatherings.) Of course he played his usual blame game, and several governors responded the same because American politics is infantile and tribal.
Addto that your disastrous unemployment system, the incompetence of your stimulus (Australia's is vastly superior in every way) and chaotically funded health care system and of course you have tens of thousands of people risking their lives and others in economic desperation protesting.
And American culture being almost totally incapable of learning from the rest of the world, insular and small minded, I reckon you will be one of the last developed countries to pull out of the pandemic and at far higher death tolls and economic cost.
Your unemployment rates is double Australia's and growing far more rapidly and your stimulus, much of which in true American fashion is being grabbed by powerful economic interests unlike ours, is not enough to keep the average American going.
The American response has been seen with horror and has severely damaged the countries credibility world wide.
