Oh I agree with you, but they can continue fantasizing that they are "God's channel" and "Christ's viceregent" while squirreled away in a lakeside compound and shooting out videos every couple of weeks.
But...
They can't feel the drug-like rush of "life or death" power of [to-disfellowship-or-not-to-disfellowship] remotely. All JW judical meetings are to be "held in abatement" per GB directive until it is possible to meet in person at a Kingdom Hall. They have a pathological need to know they are in control, they need to feel it. If no one can be disfellowshipped, that need is not being met.
They also can't feel the adrenaline rush and ego boost of having 10,000 or 50,000 or 100,000 adoring adherents hanging on their every word at a convention, then bursting into long rapturous applause, then seeing the hours-long greeting line of swooning JWs who just want to touch the fringe of their outer ill-fitting garments....
Eventually those primal desires will drive them to return to "normalcy" as soon as they can do so without appearing to be stupid or careless.
