well said! two minor disagreements: even though i like alignment more than my friends, it's not really part of 5e anymore. 5e is not perfectly balanced. if you give out no magic items magic users will overshadow martials at higher levels. also i would not mind them buffing shitty spells like find traps, witch bolt or barskin.
yeah it's a misconception that the game is balanced around martial classes having no magic weapons
The guidelines for magical weapons by level are in Xanathar's Guide to Everything, these guidelines are Wizards of the Coast's inbuilt assumptions
BG3 I feel does pretty good with its magic items, lots of alternatives and sidegrades, few power spike items
