The argument

A star made of strange quark matter could only exist if that matter were absolutely stable in bulk; therefore, if some observed compact stars are strange quark stars, the hypothesis follows. Candidate objects are those whose inferred masses, radii, or cooling behavior fit quark-star models better than neutron-star models.

Granting that some observed compact stars are in fact strange quark stars, the hypothesis would follow with near certainty, since bulk strange matter could not form self-bound stars unless it were absolutely stable. The weakness lies in the premise. The candidate-star subclaim is supported only in its weak form, that some stars may be strange stars. Every candidate also admits a conventional neutron-star reading, so the argument currently adds little.

    The inference is sound: a confirmed strange quark star would require strange quark matter to be absolutely stable in bulk, so the argument stands or falls with whether any observed compact star is in fact a strange quark star. That premise is assessed as supported, but only as a statement of live possibility: candidates remain observationally viable while none is confirmed and each admits conventional neutron-star readings. A further caveat attends the inference itself: if two-flavor quark matter is the more stable form, an unusual compact star could be an up-down quark star rather than a strange star, so even a confirmed quark star would not by itself establish the strange form. The argument supplies suggestive rather than confirming backing.

That premise is now assessed as supported, but only as a statement of live possibility: candidates such as massive pulsars compatible with quark-star equations of state and HESS J1731-347 remain observationally viable, while none is confirmed and each admits conventional neutron-star readings. The argument therefore continues to supply suggestive rather than confirming backing; it would become decisive only if a candidate were shown incompatible with any nuclear-matter equation of state.

    The inference is sound: a confirmed strange quark star would require strange quark matter to be absolutely stable, so the argument stands or falls with whether any observed compact star is in fact a strange quark star. That premise remains speculative; candidate objects exist but none is confirmed, and their properties are generally also compatible with nuclear-matter models, so the argument currently supplies possibility rather than positive evidence.
