That's a lot of over-simplified hogwash.
Motives, intentions, rights, wrongs, tension twixt, the ominous moods, the reason for being, none of this is similar.
Of course certain details like roads or money or Texas or law are going to be similar. Both are crime movies. Both are located in similar settings. Both involve people.
But nothing that ties the plot together is similar.
At udes of everyone involved included.
Your strongest point is the similarity of Bridges/Jones characters, in that each has seen it all, or mostly seen it all, brings a wealth of perspective, but where Jones was a crotchety cynic, Bridges was a mostly sarcastic-go-lucky. One was resolute to a world where he understood he couldn't solve or fix everything, or maybe anything, despite best attempts. The other was indignant and impervious to the notion that he couldn't solve or fix or correct all wrongs, badge or no badge.
Factor in one plot revolves around shady drugs, their reach and influence, and the corrupting influence of blood money, and the other is about opportune/vulture banking preying upon the weak.
At no point in No Country was there a moral righteousness to what Brolin did. He was entirely selfish. There's was no greater good. No high ground.
With the brothers, it was righting a wrong even if wrongly.
All of your superficial similarities do not mean they are anywhere similar in films.
It's like saying Heat is trying to be Oceans 11 (the original). Or that Django and 12 Years A Slave are alike.
Topics, settings, tropes, sure.
But the films aren't even close to being similar.
