Ummm… Barbarian Unarmored Defense is based off Con, not Dex. They just didn't take away the default Dex bonus to AC that every class in the game gets. They shrug off damage by having a high Con. Barbarians are pretty good as it is, if you let them completely dump Dex and give AC from Str, they would be broken AF… 18 AC at level 1 with a shield under point buy system, and immediate jump to 20 AC at level 4, with no reduction in damage output at all. Possible to be 20 AC at level 1 literally completely naked (no shield) with rolled stats, and 18 isn't even entirely unlikely…
The reason that it's broken (in a bad way) as Dex+Con compared to the Monk's Dex+Wis unarmored defense is that monks absolutely CAN get broken as fuck AC from Dex + Wis, especially as the game goes on. Kinda on a related note, in BG3 I re-specified Astarion as a thief/monk, gave him a few mid-tier magic items, and now he's my front-line tank with an AC of 21 at level 7. No sane Barbarian PC is going dex barb, so realistically the barbarian's unarmored defense is going to cap out at AC 15-16 minus shield (which, come on, what barbarian won't be rocking two handed weapons?). So, while the Monk gets unarmored defense based on both of its chief stats, Barbarian gets unarmored defense based on just one of its chief stats.
Having a barbarian with a broken AC to start with doesn't bother me too much, but then I also tend to not run gritty/from dark style games, and that's also bearing in mind that the martial classes don't really scale as well as the casters do after level five. Giving the barbarian a ludicrous AC to aspire to at high levels might help balance that out.
You are talking about removing Dex bonus to AC, which every class gets, to make Barbarian able to completely dump 4 ability scores and not even need items (at least a fighter needs nearly 1k gold to get into heavy armor that will compete with this barbarian completely naked). Barbarian is not broken in a bad way currently compared to any other martial. A monk might keep up with AC, and maybe even damage output (but I'd argue being locked into monk weapons means they won't) but they'll have at best 60% of the HP a barbarian has (who is also taking half damage from non-magical sources a majority of the time) and still have to put points into 3 stats to stay relevant.
Also, BG3 is not a great source for comparison… I have a bard at level 5 with a 21 AC. The more "tanky" classes I have played were all around 23 AC at level 7. There are a lot of magic items in the game that stack AC and you are absolutely swimming in them by level 8. Every party I've played through by the end game it was 4 characters with 23-26 AC across the board. My wizard was 24 AC (25 if standing in low light) by level 10…
You're aware that barbs get resistance to bludgeoning, slashing and piercing irregardless of whether it's magical, right? And that extends further with the bear totem

Yea, I meant to refer specifically to spell damage but wasn’t very clear. But that furthers my original point anyway.
Monks still require to have Con to be viable.
While a Barb wouldn't require to have Dex in any way.
All classes are designed to have the need of at least 3 stats.
