I know this is bait, but i have a 3d printer and it is a cool hobby. I like tuning the machine and configuring it. Also I have printed several parts to repair shit around the house, I also have printed parts to build a large CNC router.
The microplastics argument is solid, but i believe that as long as you print PLA in a very well ventilated environment and with a mask on you are not going to risk much. I belive MP and NP exposure from drinking from an old PET bottle or having polyester clothes around the house is far greater. Also if you live in a city you breathe tire rubber dust all the time.
Maybe it's just not for you I guess.
