Ask HN: Mac (book/mini) owners, doesn't soldered storage bother you?

Hello, This is a genuine question, since my wife is looking to replace her old MBP and she wants to stick with MacOS. Basically, the inability to replace the storage bothers me for 2 reasons: 1. if I have to send it for repairs I send my data too - is encryption (strong) enough? 2. I never trusted or bought a used hard drive, so buying a used MBP would mean that. Is it that reliable? Thank you in advance.
