Again, you are assuming a specific model, based on essentially no
information.

I am assuming that a quasar can be fed only by
1) gas
2) stars

Why this assumption?

Gas is not possible (heats up and stops the process) so it must be whole=

stars...

What else?

Primordial black holes.

You have no problem postulating that the big bang didn't happen, but are
afraid of considering primordial black holes?

Which is more probable: you assume that only stars and gas could
possibly feed a black hole, then find arguments against them---is it
more probable that this somehow concludes that something is wrong with
big-bang cosmology, or that perhaps your assumptions are wrong?
