The comment was made more in response to the Marvel editors who believed the marriage aged Peter and was therefor not appealing to kids, rather than the video itself. The sentiment you described in the post itself (albeit being sarcastic), so I was responding to that more than the video.
To be honest, the video itself seems to be more put up job than anything natural, so I don't really feel comfortable proclaiming it as evidence that fans of the marriage "were right".
