Yes, but you do not lose scars when you stop getting cut, and scars are also the body's protective mechanism.

No, scars are not protective mechanism. It is an organism fault to correctly restore damaged flesh. Protective mechanism in case of wound is blood curling to stop bleeding and limphocites to get rid of bacteria and dead flesh cells. As danger is mitigated, this protective mechanisms are completely disabled and everything returns to normal.

If you want this model, then the theory will sound like "poison irreversably damage body system and it began to produce fat". Slightly different comparing to what described in OP.

these are examples of the body not healing fully after being damaged.

But it is another theory, far from "fat is a protection from poison".

PS: And PTSD does not exist.
