'We're going to force workers into the office and hope they do some work out of boredom' is taken as a serious strategy because the average manager is mind-bogglingly incompetent. If you know how productive people are (i.e. your managers aren't morons), and you have incentives set-up (e.g. pay, promotions and hiring/firing is dictated by productivity), then there's no problem to solve. Workers who are more productive in the office will be forced into the office to meet standards, you don't need blanket rules.
