May I ask who wrote this? Reminds me of a Solange Hertz exercise in creative writing.
In point of fact, there's no evidence that obelisks were phallic symbols. It's easy to impose that interpretation on them, but we actually have some descriptions of the earliest ones in Egypt as being related to the sun god Aten, where it represents a ray of the sun, pointing up at the sun. Related to this, some also believe that they served the purpose of being an astronomical marker and effectively a sun-dial. And they were also installed as boundary markers where something on the top would basically say, "I, Emperor Such-and-Such lay claim to this territory". In all such cases, it would be consistent with how the Church had appropriated other pagan symbols, by re-interpreting them. So instead of the obelisk pointing up to the sun god, they point up to the Son of God (English pun, I understand, but the import is true). It also symbolizes, with the cross on top, that Our Lord rules over the territory. Finally, looking at it from above and viewing the rest of the architecture, it also looks like the part of a key that gets inserted into a lock to open it, referring to the keys of St. Peter.
While I'm fine with criticizing some of the garbage at the Vatican, including the pagan gods they keep in the Vatican museum. I'd sell that garbage to museums around the world (you could probably get billions for it). I'd also sandblast the Sistine chapel ceiling to remove Michaelangelo's homoerotic junk.
So I'm not opposed to criticizing the Vatican art/architecture (as if these popes were infallible in that regard or it would be considered impiety to do so) ... just that in the case of obelisks, I don't believe they were originally phallic symbols based on the actual evidence. It's easy for people to imagine that due to the shape, but there can be other explanations, and the evidence points toward those other explanations.
