I can appreciate wanting to do things yourself. Maybe it saves money, maybe it makes you feel handy around the house, or maybe it just allows you to indulge your creativity.
Speaking for myself, I am not handy at all. I'll always pay somebody else to handle something for me if I can afford it. And if I can't, well... it just doesn't get done.
But these people have more wherewithal than I do. They're doing their thing their way, and frankly, I don't think we can stop them.
So, let's just enjoy them!
