Wouldn't an example be a job that requires it? Are you attempting a meta comment, and really mean something like "anyone can quit a job that requires social media usage"?
Your statement does not take into account related factors, e.g. you have a job you like and need, but the job changed to require social media use; you love and help a remote family member who prefers using social media to stay in touch, etc.
In some similar statements, e.g. "If you don't want to be in car accidents, then don't be in them" the logical flaw is clear: Prevention involves a number of steps and assessments, skill, and some luck. Changing it to say "If you are concerned about car accidents, stay out of cars" would be equally problematic.
Those who care and have to use TikTok can probably add their own virtualization layer (and tolerate the hit in cost/performance).
