  Starting from the Oppenheimer-Snyder model, we know how in classical general
relativity the gravitational collapse of matter form a black hole with a
central spacetime singularity. It is widely believed that the singularity must
be removed by quantum gravity effects. Some static quantum-inspired
singularity-free black hole solutions have been proposed in the literature, but
when one considers simple examples of gravitational collapse the classical
singularity is replaced by a bounce, after which the collapsing matter expands
for ever. We may expect 3 possible explanations: $i)$ the static regular black
hole solutions are not physical, in the sense that they cannot be realized in
Nature, $ii)$ the final product of the collapse is not unique, but it depends
on the initial conditions, or $iii)$ boundary effects play an important role
and our simple models miss important physics. In the latter case, after proper
adjustment, the bouncing solution would approach the static one. We argue that
the "correct answer" may be related to the appearance of a ghost state in de
Sitter spacetimes with super Planckian mass. Our black holes have indeed a de
Sitter core and the ghost would make these configurations unstable. Therefore
we believe that these black hole static solutions represent the transient phase
of a gravitational collapse, but never survive as asymptotic states.
