Face covering even if you consider yourself distanced is necessary due to 1) the inability to reliably re-don the mask once you’re no longer in a distanced condition; 2) reduce mask touching; and 3) the fact that 6ft is not a magical line especially when there is shouting and people are elevated over one-another.

People cannot keep their distance from one another and, when in a conversation or queue, will naturally and unintentionally close their distance to 2ft or less. Instead of frequently doffing and donning the mask or asking people to memorize and follow a specific set of conditions and distances over which to use one, it is much simpler both from a personal and administrative perspective to just keep it on the whole time.

All I see is an explanation and reinforcement of what was already in place (which is fine).
