Consider that the more these hypothetical mutations accumulated in a genome, the more likely it would become that the next mutation will be slightly beneficial. Even chance alone would establish an equilibrium.
This may already have been answered a dozen times over, but isn't it the case that apparently neutral mutations that have been carried along in the genome for whatever reason can then capitalize on additional mutations that have beneficial effects but that might otherwise not have been possible? Actually, isn't that what you're already saying here?
