Yes, but for those examples there are other barriers to entry.
To own your own home, you have to make a large financial investment.
And hire a qualified electrician to install cabling inside the house, to reinforce your point.
People try to draw a line between electric cabling and using a computer, based on the false assumption that if you screw up electric cabling you die, whereas if you screw up your own computer, it only affects you.
That's a bogus assumption because the reality is that we have this thing called the "Internet". You know, a community of networks, where computers actually talk to each other. And, you know, cause havoc on each other's networks.
If you crash the car in your own paddock, that's okay -- it's your car, and your paddock. But if you drive irresponsibly on the road, especially a highway, which is a commons of road drivers, you suddenly have the ability to cause a lot more harm.
It's the same with the Internet. If you own a PC, and you connect it to the Internet, you have a responsibility as a citizen of the Internet (and the world, pretty much) to be conscientious to others. An infected PC is not a laughing matter — you’re actively harming someone or something whether you’re aware of it or not. If you're not prepared to take due care, you should be treated like the cops would treat you if you were an unlicensed drive — you shouldn't be allowed on the Internet.
It's a social problem, not a technical one.
