Less than the amount of difficulty added to driving a car that can only be adjusted by poking at a TV mounted some place where you aren't looking at the road. Sure, fixing that squeaky door is "easy," but have you ever heard the adage that every home project involves three trips to the hardware store? There may be technical aspects that few of us can implement from scratch and on the first try, but at the same time I also don't know how to build a good broom. These concerns are not insurmountable, especially with the network effects of people being in the same boat. How easy is it to find a good handyman without asking anybody? You don't have to.
