So in my basic understanding, the absolute value of a TD pass= 6, and the absolute value of an INT <6.
Another way I could say it, is if you took the avg points awarded for all the TD passes ever thrown in the history of football, it would be 6 points to the scoring team. However, if you took the points awarded off of all the interceptions ever thrown in the history of football, it could not even be close to 6 points to the scoring team, I could even see it being close to 2, because of all the times 0 points are scored off of an INT.
Not being a smart alec, just don't see how an INT is worth 2 or 3 times a TD pass.

By really smart people, I was referring to people much smarter than myself.
Now, I've seen versions of this analysis in multiple places, but I'm going to link to research done by pro football reference, because, well, it's easy to find. I think the original groundwork for this was done by economists Palmer, Thorn, and Carroll (also way smarter than me) in the Hidden Game of Football way back in 1988 (so their research predates me...as in me the person, not just my research).

PFR has always done a 45 yd penalty for INTs and a 10 yd bonus for TDs. They've recently upped their stats to included a 20 yard bonus for TDs because there's a lot of debate about how valuable a TD pass is compared to a pass down to the one yard line, and it's probably really context heavy no matter what, so the estimate could be way off. But not so way off where an INT and a TD would be of equal value.
If they were of equal value, you'd want a quarterback who threw INTs and TDs at a 1:1 rate to pass on pretty much every down, despite the fact that a guy who throws 20 TDs and 20 INTs in the same year is probably not a great quarterback.
A lot of this is conjecture anyway, and your points are completely valid. That's why I'm linking and not disputing.
