"...become negligent in their 'faith practice,' the RCC is not satisfying the needs of its flock."

No church is satisfying the needs of its flock across the board, especially in the US, given the hemorrhaging among all denominations. And it could get worse, too, dropping from 71% of the population being Christian to 61%. We'll see. But every church is serving the needs of some of its flock, though not all, owing to it theology, tradition, and degree of pastoral care. Whether there will be exiting flocks or whistles of departing trains, withdrawing from these "unhelpful" churches to found a new church -- "His church" -- is absurd. Some disgruntled Episcopalians, for example, have left their church to found a new church, a new "His church," and it has come to nothing, practically speaking (especially since they lost in the courts -- taking church property, household removals with them). Exiting from one church to found a "new church" -- a church apiece -- is not a modern invention.
