Rather, part of a point by point rebuttal.
To stay on topic, this seems to be one aspect in it that requires my attention:
This can be understood as only invoking it insofar as fire being purifying
Bingo. That is all the Purgatory is: purification preceding the entry into Heaven,necessary for some but perhaps not for all.
Bingo is not like purgatory either. “All” in essence, sure, but its the developed details that have been the issue.
As shown, among other aspects purgatory is contrary to 1Cor. 3:15 in time (2nd coming, not commencing at death) and in type (of loss, which is not one's own character defects which gains him entrance into glory, but the fruit of such, that of converts, a loss which the builder is saved despite of, not because of).
The question is, where does the Scripture teach purgatiory as a place of final purification of a saved believer? I gave the answer and you agreed "in essence". Like in any question, multiple interpretations of an allegorical passage exist; that does not change the answer.
2nd coming, not commencing at death
This reading is possible, but not the only possible. The passage simply says that the man is tested according to his works and that the Day of the Lord shall make the results of the test manifest. It does not say that the testing itself occurs at the second coming.
not one's own character defects which gains him entrance into glory, but the fruit of such
This is not a distinction that means anything, let alone invalidated the Catholic teaching which generally and biblically holds that we are tested by our works.
that of converts
The text speaks nothign of "converts"; it says "every man's work"
