Your argument is still not great.... it is not physically possible to ”ski” without a device called “skis” that fit on your feet. On the other hand, it is physically possible to get on a ferry boat, or watch a parade, or sing along to “It’s a Small World” from a boat with or without a mask.
A better metaphor might be: if a business requires an NDA in order to have a job with them, either you accept the NDA and take the job or you decline the NDA and don’t take the job. If you take the job and break the NDA there are consequences.
