It wouldn't have given me any heartburn to close cruise ships in April 2020. Like I said I give the first couple of months' policies a mulligan, including school closures. Maybe its more correct for me to say I opposed lockdowns that lasted more than the first couple of months.
However, you seem to make the assumption that without government intervention that their would have been no protocols followed by business. That couldn't have been farther from the truth as evidenced by essential businesses that took significant precautions even if they weren't mandated to do so. We were an essential business (although I'd argue far less essential than schools) we took precautions beyond what was required. Restaurants were more than willing to take the business outside if allowed among other precautions to remain open. Were there some businesses that might not have done so, sure those businesses that are not reputable and don't understand risk management. That happened whether they were forced by the government or not to close. Plenty of non-essential businesses open during the lockdowns, some who lived paycheck to paycheck had no choice, like many hairdressers.
I'm fairly confident that cruise ships would have delayed trips in the early months of the pandemic for risk management purposes, they didn't need the negative publicity of mass infections or deaths on their ships. A prudent business policy would have been a requirement for passengers to provide a negative Covid test.
To sum it up your apparent assumption is that businesses would have done nothing without government intervention to protect customers and employees is erroneous.
Your dependent on the government for your livelihood, so you sound more comfortable with government intervention into others lives as a result. Government and particularly bureaucrats are often a hindrance in my livelihood, so that's why we sound like were from different planets. Reality is that were just from different backgrounds.
