The friction pressure that keeps the cable in place is provided by the cable head, while the bit inside the computer is just a solid block with nothing that flexes. Rough handling can still damage the latter, but otherwise its expected lifespan is long enough to put in the 'don't bother worrying about it' column.

From what I've read, the USB-C cable does have a pair of springs (one on each side, pressing on slots on the sides of the "tongue"), so it's not just friction that keeps the cable in place.
