Protesters in opposition of stay-home order gather at Michigan capitol

Are you sure that it was her who said you couldn't buy seeds and plants, or the store itself?

You're bringing up three entirely different points so I'll address each of them.

"Even if they all get infected, half will show no symptoms."

Don't confuse presymptomatic with asymptomatic. There is a period of up to two weeks in which a person carries the virus, is contagious but eventually gets symptoms. They are the majority (75%). People who remain asymptomatic are in the minority and tend to be under 14 (25%).
This is based on a small Chinese study. I would like to see ongoing research to see if it holds true in the U.S. especially since our virus is a different version.

"Only 5% will get very ill."
No. 5% will end up hospitalized. People not admitted are still becoming very seriously ill - can't breathe, too weak to stand, vomiting, diarrhea, etc.. Another thing is that some of these people are experiencing a sudden downturn and dying quickly in their homes. The lack of oxygen is stressing the heart and other organs and the central nervous system.

"... California shows the actual infection rate is 50-80 times official numbers!"

No, the study was limited to Santa Clara County and reported 2.5 to 4% infection rate which is too low for herd immunity (50%). The virus has different contagious rates in different regions throughout the country based on different factors like density, government response, time of infection, etc.

Another issue is that some people who had the virus and recovered are becoming sick again. I read a study saying some people are not getting enough antibodies after recovery to avoid recontagion. That's scary!

More research is needed. In the meantime, try to not get infected with it. Vaccine and/or treatments on the way!

What's more, Whitmer has decreed that violations will count as misdemeanors punishable by up to a $1,000 civil fine. Criminal penalties are also on the table, should prosecutors choose to pursue that. Meanwhile, Michigan Attorney General Dana Nessel has gone full China and is encouraging employees to rat out their bosses and call the police if they try to open up shop in violation of the lockdown.

What's so outrageous about all this is that the new businesses and activities that Whitmer is targeting can all be safely conducted while adhering to strict social distancing rules. But Whitmer's theory apparently is that anything beyond absolutely essential conduct jeopardizes frontline workers. This is the precautionary principle on steroids. It considers even an infinitesimal increase in secondary risk as unacceptable, a mindset that could justify stopping virtually any activity anytime.

That's why this order has disrupted the political equilibrium in support of her efforts. To date, hardly any legal challenges have been filed against any stay-at-home orders. But Whitmer's new order has already prompted four Michigan residents, including the guy who can't see his girlfriend, and Contender's, the landscaping company, to sue her for violating their right to free association and perpetrating an uncompensated regulatory taking. More lawsuits might well be underway.

Meanwhile, Operation Gridlock, which was mounted by the Michigan Conservative Coalition inviting motorists to drive to Lansing, the state's capital, and shut down its roads, elicited a massive response Wednesday. Thousands of Michigan residents heeded the call and created an hours-long traffic snarl.

Although the motorists adhered to the social distancing rules as they were advised, the protest also brought out a lot of nasty gun-toting thugs onto the streets. Michigan Proud Boys, a supremacist outfit, blocked the intersection around a hospital. Not only did they ignore safety guidelines, exposing themselves and others to the virus just when Michigan was beginning to flatten the curve, they also waved Confederate flags and chanted "lock her up."
