In the end, that really doesn't matter.
If there are not enough priests to provide the sacraments to the faithful, then the Church must do something to address the problem.
That may mean importing priests from countries with an overabundance of them.
Or it may mean altering the clerical celibacy requirement.
But to deprive the faithful of the sacraments when they don't have to be would be objectively sinful, don't you think?
