>There can never be "proof" that "return to office" is "pointless." Setting aside a possible uninteresting conversation about the semantics of the word proof and discussions of the nature of falsifiable hypotheses that were last interesting when we were in junior high, zero average change in stock price or negative average change in stock price would be a strong signal that return to office is pointless. If the statistical significance of the result were strong enough, I would absolutely consider such a result "proof" that "return to office" is "pointless." This research may or may not clear that bar (it's hard to tell from the linked summary).
