Because your immune system isn't guaranteed to pick up on the most relevant part of a pathogen.
While lots of people got diseases like smallpox and measles only once, others would get them several times. The difference is what part of the virus your antibodies selected to attack.
The spike protein seems to be both extremely important to SARS-CoV-2 and relatively unchanging.
If your body creates antibodies to it, you will have immunity on par with the vaccines.
If your body doesn't create antibodies to it, you have a mixed bag of immunity. Getting a vaccine buffs that up.
Immune systems are very buggy learning systems. This is good from a species survival perspective, but not always for a specific individual.
