Priests sure are on call 24/7, and there are just not enough of them. Mandatory celibacy is the number one barrier to young men entering the priesthood, and removing the requirement for diocesan priests would solve that problem practically overnight.
I do acknowledge that neither the East nor the West has ever done married bishops. What this means for the priesthood, though, is that married priests know they will always be diocesan priests. You know how with some priests you know they’re treating it as a stepping stone to another position? That would never happen with married priests.
Additionally, with some priests being married it would not mess everything up. There are married priests in this world and it objectively does not mess things up, not just in theory but in actual reality. Married priests operate a bit differently than the celibate ones, they serve at only one parish and travel a lot less, and their hours are a bit more flexible in order to allow for family time. Celibate priests wind up being more flexible comparatively speaking, but this is something they already do- they would just have to do a bit less of it on account of the priesthood becoming at least 50% larger all of a sudden. Not only would it not mess things up, it would operate more smoothly than it currently does, considering how so many parishes do without any permanent placement and this is a relatively light priest shortage compared to anywhere south of the United States.
As for female deacons, perhaps they aren’t needed. And it looks like that’s your preference as well. But some other people have a different preference, and that is what was inquired after by the OP. So what you should do is nicely ask what the reasons are for such a preference and don’t immediately down-talk people just because they did exactly what was asked of them- which is to say, express a non-Catholic preference for a non-theological change.
