just wanted to say that i mostly agree with OP and that this opinion also seems to be quite popular and often discussed.
btw handing things to other people and grabing things out of your backpack are usually not bonus actions but free actions (interacting with an object).
and by the rules drnking a potion isn't even the "use an object" action but the "activating a magic item" action. (even though i'd disagree)
