I mean, do you do everything around you yourself? Do you fix all your appliances, do the plumbing in your home, do your own health check-up, complete car maintenance and repairs, all the details of your finances, and so on?! Probably some of it, but we all have things we cannot do ourselves, or where it just makes sense to let people with more knowledge and experience do it for us.

For many computing is exactly that, I guess because the abstract logic of computers just doesn't come natural to them, and it can be very complicated if we are being honest. There is extensive customer support in that field for a reason. I'd say the majority of people couldn't fix a broken package installation if their lives depended on it, not without substantial time investment, education and training.

You just can't expect most people to know how it all works and be able to fix everything themselves , but they should still be able to enjoy the benefits of free software imo. Just like I can keep my home warm in the winter without having intimate knowledge about how my heater works and being able to repair it myself. I can just call the landlord and get it fixed the next day.
