This isn't rocket science: No one is denying that you've gotten a workout on your stationary bike. No one is claiming that you didn't derive some benefit from sitting on the trainer for however many hours you did. But you didn't go anywhere, didn't cover any distance, you remained in one spot for the entire duration of your Zwift session. And so "miles" is not the correct metric to measure whatever it is you're logging from that session.
Actually, I covered a lot more miles than you think.
"The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour."
