I'm not sure I understand your argument, but if large portions of the genome have no effect on phenotype, then perhaps we can both agree that those regions would not be under selection. Pressure on the phenotype cannot directly alter the genotype (no Lamarkism), but it could select for or against the fraction of the population with a particular genotype. But only if the genotype produces a phenotype.
