I was clarifying the sense I was using the term "force field". Not a generic field of electromagnetic forces, but the fantastical one that can contain arbitrary matter.

Like the one described in the article, that a person was leaning against and could not pass through. If this were something that we could reproduce, it would have awesome real-world uses. Like a real hover board! Or the best anti-theft protection for my parked car.

You could though. Given a sufficiently strong enough positively (or negatively) charged electric field and yourself equally positively (or negatively) charged sufficiently you could have an 'invisible' wall that you couldn't walk through. Assuming that neither yourself or the field you're walking into has anywhere to discharge to.
