Bondi-rate consumption in dense matter
The argument
Because a captured micro black hole inside a white dwarf or neutron star accretes at approximately the Bondi rate, and the Bondi rate at compact-star densities implies consumption of the star within millions of years or less, while old white dwarfs and neutron stars are observed to survive for billions of years, a rapidly accreting captured black hole would destroy its host well within those observed ages. Given that a black hole accreting hazardously fast on Earth would accrete faster still inside white dwarfs or neutron stars, whose densities exceed Earth's by six to fifteen orders of magnitude, the margin only widens for the rapid-accretion scenarios the claim addresses.

The inference is sound: given Bondi-rate accretion at compact-star densities, consumption times fall orders of magnitude below observed stellar ages, and the density scaling makes the conclusion robust for any black hole rapid enough to matter. The argument lives on the Bondi-rate premise, which is standard first-principles accretion physics though not yet assessed on its own page; the observed longevity of white dwarfs and neutron stars is uncontested, and the density-scaling comparison with Earth adds a wide safety margin that absorbs model uncertainty.
