So was my thoughts about debris correct. If it becomes a shitshow does
it clear itself out in 5 years?

A generic calculation for a 500km orbit gives you around 10 years. The
design of the starlink satellite is somewhat optimized for this in that
when it is controllable it presents a knife edge to atmospheric drag but
uncontrolled it will slowly start to tumble and degrade much faster. ~5
years at 550km without looking it up.

SpaceX states that at the current service altitude, the satellites will
be-orbit in ~~ 5 years. That's one of the reasons they went with the
lower service altitude. The original was up substantially; perhaps
where
the 10 year number came from.
