And I don't think its an easier strategy. Both strategies require quality draft picks being taken. If you can't draft well, neither strategy can be effective in any scenario.
So your opinion is that it's easier to have more money to spend in FA and buy assets AND rotate mid-tier QBs every 4-5 years then to simply pay a high end QB market value and then buy cheaper assets with less money.
I've not seen an argument yet that suggests or validates that as an "easier" task. It might be "easier" in a 4-5 year stretch, but long term, I don't see that model being effective at all. I think you'll trade a small window of being relevant for many years of average to below average play, and you'll get many GM's, coaches, and QBs fired along the way.
Too many GMs will acquire FA assets that won't live up to their comp, get injured, etc., and too many GMs will whiff on being able to attain even a mid-tier QB in the draft (or FA) in a 4-5 year window.
And for the record... I think your strategy CAN work for most positions EXCEPT QB. I think it can definitely work with WRs, RBs, and various positions on the defense. I think teams can and will absolutely start declining to pay the franchise WR $25-30M a year in favor of draft picks or mid-tier WRs, because they're much more replaceable than QBs and because they're starting to cost as much as a mid-tier QB would anyway.
