I think you’re way over stating what Q was & still is.
In may opinion a way too complex an explanation. (I acknowledge it’s possible you’re right!) Apply Occam’s Razor it becomes harder to make the case !
It was a LARP that became a grift.
It was utterly implausible in its explained origin from the very beginning. It’s origin, explanation of “Who Q”, “Why Q”, “Where Q” and “ Q sourcing” changed over time as it was challenged & particularly when it failed to produce. (Hillary arrested, Huma arrested, Trust Sessions {He was like Arthur sleeping on the Isle of Avalon !}, Huber has 60,00 indictments .. I could go on!, etc.) All typical behaviors of fraud. It took advantage of peoples desire to participate and help the Trump revolution by manipulating their confirmation bias. Goal was to gain enough of a following to generate hits at web sites to create a revenue flow. Make a market for Q paraphernalia. (Saw it at rallies!)
Did it hurt Trump in the re-election run? Maybe but I don’t think by much. Did it encourage the fantasy prone Q-sters to go and participate in the recent Capital Hill PR debacle. Again maybe? I think the trouble was primarily due to ANTIFA infiltrators.
The Q phenomenon reaffirms the idea that the Internet is full of a nonsense even nonsense you may well like and agree with, That’s when you need to be particularly on your guard !
Combine Qidiots with Antifa to light the fuse and you have the Capitol hill riots where Trump lost the message and it played right into the deep state’s hands.
