If strange quark matter is the true ground state of matter, it must have lower energy than nuclear matter. Simultaneously, 2 flavour quark matter must have higher energy than nuclear matter, for otherwise the latter would convert to the former. We show, using an effective chiral lagrangian, that the existence of a new lower energy ground state for 2 flavour quark matter, the pion condensate, shrinks the window for SQM to be the ground state of matter and sets constraints on the current strange quark mass and the sigma particle mass which may be precluded by the data and thus point to the implausibility of SQM being the true ground state of matter. In consequence, this points to the implausibility of strange stars and also almost eliminates the doomsday risk of the world being eaten up by strangelets produced at a heavy ion accelerator. Further, this analysis provides the unexpected bonus, that the phase diagram of QCD at finite density is such that chiral symmetry remains spontaeously broken at all density!
