The rapid test isn't very accurate especially in the absence of a full blown infection. The annual cost of doing a PCR test twice a week to ensure you always have an actually accurate test within 72 hours of working would be around $15,600. This is about 43% of the gross individual median income.
For practical purposes employers can't afford to pay near 50% more for the least reasonable employees, the government isn't incentivized to do so to make it easier not to vaccinate when this is really a poor substitute insofar as public health, and only the minority of employees can afford this.
In effect the end result of a practical testing alternative is to pretend we are giving them a choice while in fact giving them little choice.
