All of those things you listed are totally normal for people to DIY. It's kind of bizarre to me that you think otherwise. It's like when Randy on South Park teaches his kids to call the handyman to fix the oven door. Or there's a handyman on youtube who's talked about being called and charging people like $500 to push the button on a GFCI outlet. It's hard to believe he's serious. He's also talked about being called by millennials to change smoke alarm batteries.
