FWIW, my "it may even be arguable" objection was to the specific "on order to obstruct justice" part of this claim: "In this case, kidnapping in order to obstruct justice may even be arguable."
In _my_ opinion, anybody who argues they've been "kidnapped" if being told they can't leave an event which advertised itself saying "once the event starts you won't be able to leave for two hours" is most likely being unspeakably self centered and disrespectful of everybody else's time and rights. Sure, there are exceptions - and if event staff _really_ tried to enforce the agreed-upon no-exit policy in the face of medical emergency or obvious external need, perhaps "kidnapping" would be the right (or one of the useable) legal remedies, but going down that path for claustrophobia or panic attacks will result in me judging you in a _very_ unfavourable light - in much the same way as I'd be extremely unhappy to have my flight diverted for a panic attack.
In your professional/ambulance case, there's at least one big difference - people don't specifically get asked to agree up front that once they get in the ambulance the deal is they agree not to get out until the end of the ride. And I've got a question - where does practical reality come into conflict with your risk of getting charged? If I demanded to get out of your ambulance immediately, whould you stop and let me out in the middle of the Golden Gate Bridge or the Lincoln Tunnel?
You are talking about matters of etiquette & consent. Consent can be granted, but it can also be revoked. The woman in question apparently ceased her attempts to leave when presented with two bouncers who intimidated her in some way. This in itself may be, in American legal parlance, 'assault', the threat of force, used instrumentally in order to accomplish kidnapping. But it begs another question: What exactly would have occurred if the woman had not taken 'no' for an answer? The men were there to tell her not to leave. The men were chosen for their physical characteristics that conveyed an implicit message of 'we are able to restrain you if we have to'.
