The devil is in the details but I generally agree with this. There are married Catholic priests now; these are mainly in the Eastern Rite Catholic churches, but they also include a scattering of already married clergy from other denominations who converted to Catholicism after both their marriage and ordination. And deacons are generally married.
The Latin Rite church adopted the discipline of celibacy in the Middle Ages in response to chronic problems related to money and property. The RCC traded one set of problems for another. The lack of vocations and the homosexualization of the clergy are today far greater problems than potential misappropriation of funds by married priests. The RCC could easily retain the discipline of celibacy in some orders while allowing married clergy in many roles.
I guess I should have said Roman Rite instead of Latin Rite, but the point stands. The Eastern Rite Catholic churches have always had married clergy.
Clerical celibacy in the West was the normative discipline long before the middle ages, and had nothing to do with property.
