Not everyone can do everything. What may seem easy or trivial to us isn’t to many. A lot of people don’t want to deal with tech just use it, either by choice or just aren’t the kind of person to get it (and that’s not necessarily a bad thing). Just like I hate doing plumbing, and for most things happy to pay a plumber. And for simple tasks like fixing you toilet flushing, they make a nice little kit all ready to go you can get at the hardware store.
