I don't want to be protected from myself. As the admin I should have full access to the stuff I buy.
Disabling it is ok but the problem with that is that you lose all security. There should be a way to add our own signing keys to persist changes to the SSV (Signed System Volume) and SIP protected folders. It shouldn't be trust only Apple or nothing.
They shouldn't have the same rights? Just because someone is less technologically aware today, you think it's OK to start stripping away their rights? That's like saying poor people shouldn't be allowed to own a house because they won't be able to afford the maintenance.
The more accurate version of your analogy is that they can choose to do their maintenance, they just won’t be covered by insurance (their own or that of a tradesman) if something goes wrong.
That is actually how it is in reality, and maps very well to as analogies to the two levels of SIP.
The new cryptex mechanism could be used to allow persistent modifications to the SSV (that's how it's done on the iOS Security Research Devices), but no idea if Apple will actually implement that.
