I didn't blame them. I said it is impossible for those who need it to get help on their own, and therefore it is not their fault. The system needs to provide some way for someone to help people who need help get it because people who need it will not be able to get it on their own.

OP probably isn't as bad as some I've met who cannot even open an unlocked door with a handicap button on their own. Such people exist though, and somehow the system needs to ensure those people are not lost (including finding them!). Once you have that in place you may as well use the same people who get help to need it.
