I did the same. I was inspired by The Beatles box, went all out with a Miyajima Zero setup (including SUT and mono phono pre), but finally concluded it was slightly irrational to justify the expense with only 100 or so mono albums. 80% of those were reissues anyway, so they were cut with a stereo lathe.
That said where the mono cartridge fanatics are correct is with original mono albums (pre 1964 I believe). The few old jazz albums I have sounded amazing with the mono cart, and noticeably superior to the mono switch on my phono pre.
So I agree with you but with the large caveat that for those with an extensive original mono collection, a true mono cart is indeed the best option.
