I didn't say they'd exist forever, just that they'd continue being around. Apple could profit $0 for the next decade and have enough cash-on-hand to continue operations for several years. It's not realistic that Apple would cease to exist immediately anyways - that's not how antitrust works.
If Apple dematerializes one day, I give you full permission to intrude on my latest comment and break the good news. There are two champagne bottles I'd like to open and I've been saving them for such an occasion.
