I like to take care of my stuff. Principles. I tend to use my cameras far more heavily than most people. I often take a batch of technical photos and then swap the card into a reader or PC to download, so on some days I may do 10 card changes. Nt every day certainly. I have never has a camera card insertion problem. I have had a number of card reader issues of a range of sorts. And I have had numerous mini-USB socket and plug problems. I'd be happy that an SXD card socket in a quality camera will outlast the shutter mechanism for most users. When the shutter fails (50,000 to 200,000+ actuations depending on model) you could get them to change the USB and SD sockets at the same time.
