6) Equipped weapons are carried very strangely, they seem to be attached to the back by some force field. How does that work? Also it is very impractical. Why not have swords in scabbards, arrows in quivers, and longer weapons carried in hands? The only one that carries a weapon in hand now is my Tav. She has acquired a flaming sword and insists on carrying the flaming end in her bare left hand.

How is weapon on back less believable than several tons weight lizard being able to fly ... person being able to defile gravity by his pure power of mind ... or fire that burns without burning anything?
When it floats six inches away from your back but remains stuck to you, and this happens for everyone and every weapon... it is.
I'll field this one, though it's a take-it or leave-it answer; I'm very confident that this is the dissonance that so many people experience about this and which you apparently don't, but here it is as best as I can explain:
Notice how everything you compared this to are intrinsically magical creatures or literal magic? As in, defined, quantified forces written into the world lore as part of tangible elements greater than themselves? Magic is a part of this realm, and it makes sense within the space of the realm it's written for - it has structure, form and rules that have been built up and defined. Most magical fire, because it is magical fire fuelled by the weave for its effect, generally does not remain around after the spell has been cast? In some cases, it can be maintained through concentration, and in some cases the initial spell burst of fire can ignite mundane objects in live, non-magical fire... but the magical fire itself doesn't stick around. This is part of the deep and wide-spread system of magic that permeates the world. So... when someone USES magic in this realm space, and they are a spellcaster with the capabilities to do so, this not only does NOT require ANY suspension of disbelief at all - it actually helps to deepen immersion for the viewer.
Now... comparatively... When the barbarian slings their axe over their shoulder and leaves it floating in mid-air behind them, glued by invisible force and distance to them... that's just silly and destroys immersion. There IS no magic involved here, and no other in-world tangible explanation.
If you cast detect magic on this barbarian you will not detect anything - and this can be tested! The barbarian didn't cast a spell, and they could not do so anyway; they have no enchantment upon them, and no enchantment exists upon the weapon to explain this - it is a direct "You're actually playing a video game" world-break that pulls a player out of their immersion in the space to see it and notice it. It's a visible game mechanical element/limitation that's waving itself in your face while you're trying to play the game... and it's doing so constantly.
In short... you're comparing apples and elephants and asking why some people say that one of them fits in the freezer but the other doesn't; it's obvious to the people who point it out, and the only intelligible reason why you aren't seeing the difference seems to be that you personally have never actually put anything in the freezer at all - not really. This may not be the case, and I don't want to presume it is, but it is all I can think of to understand how you came to stand in a position that leads you to even ask a question like that in the first place.
Larian have always struggled with the concept of immersion in space. In comments made in interviews about their previous games and in the early days of BG3's development, it seemed almost like they legitimately didn't understand the concept, or why people would find it to be important. They came to grasp that this was something that people wanted and valued, when working on BG3 but still don't actually really seem to understand what it is, what preserves it, and what shatters it... and they also don't really seem to grasp why repeatedly breaking immersion for the sake of 'doing a funny' doesn't leave general immersion intact the rest of the time - it just doesn't, when that's a regular occurrence. They don't understand why being able to "burrow" into a cage that's hanging twenty feet above you in open air is a problem, or why it breaks immersion, or why you should not be able to do that. That's the problem.
All of this is subject to change of course; communication has been precious thin from beginning to end and it's always possible that they've taken time to learn and really begin understanding this concept since their last commentary on the matter... we can but hope.
