They might be overreactions on your end Razz, but few of the lines you list are inflated like you may believe. I know you're relatively young, but people have blindly had this logic for years. "Bet on teams after losses, because they'll be soooo pissed off the next week" often seems to be the general consensus. Often times said teams just aren't as good as previously thought, or tend to take losses as negative instead of positive motivation the following week.
I had a buddy that used to work for the LVSC, and they would regularly inflate lines for a previously top ranked team coming off of a loss for the very reason you believe is groundbreaking thought. I can remember several years back him saying they had further padded a Texas line after they had just come off a loss because the general consensus would be that they would further pour it on Baylor or someone like that.
I know you love the game and probably already know this deep down, but virtually any tactic that you brainstorm that you believe is the new innovative way to take down every sportsbook has most likely been thought of and accounted for years before. It never hurts to pull up old stats and plug numbers to test any new theories you might have though. GL and I hope you do come up with some previously unknown way to make a fortune buddy....
