The center of your tire tread doesn't appear to be bad, although the edges have some aggressive tread. The problem with that is that the tube can get some uneven stretching and potentially pop due to being over-stretched. But, that may not be immediate. It could do permanent damage to the tube, but overall not a big loss.

You likely will have enough rubber for a couple hundred miles of riding. Then it may take some time to chew through the threads.

Overall, it may be a fun experiment, but I don't foresee any earth changing revelations.
