It is counter-biblical. It’s blocking religious service solely on grounds of marital status - a rather serious non-sequitur, seeing as Paul encouraged those inclined to do while giving absolutely no exclusionary basis (he said service may be harder for those who marry, but in no way indicated such people should give up service). Note also the warnings against associating with those who would prohibit marriage for religious reasons.
See, you’re thinking like a liberal, like one of those who talks about the “right” to serve in the military. The priesthood is no-one’s right, nor a moral necessity, and if anyone’s thinking of it as a means to power or authority (as the womynpriest moment incessantly does), they’re the last people we want to be priests.
I don’t know of any passage of Paul’s encouraging the reader to seek the priesthood, so I wish you’d include a passage or citation to support your assertion. That passage about celibacy is actually for everyone, not just priests.

No-one is prohibited from marrying. It’s like military service in one way: The first amendment gives our military leaders the freedom of speech. But they have chosen a vocation which is incompatible with expressing contempt for their commander in chief. If they want to campaign against the president, they still have that right, but not as a military leader, because the two roles are in conflict.
You also make the mistake of equating, “not expressly stated in the bible” with “contrary to the bible.” The bible explicitly gives Peter, singularly, and the apostles, collectively, the authority to declare that what they bind on Earth is bound in Heaven. The doctrine of sola scriptura, is self-contradicting inasmuch as it is not in the bible, and is actually additionally contrary to the bible. Were it only a matter of people saying, “I cannot find that it in the bible, therefore I will not base my faith on it,” it would hardly have been the danger and destroyer it has been. But how destructive is the further leap that “I cannot find that in the bible, therefore it is contrary to the bible, and all those who assert it are promoting heresy, and must be opposed!”
