Fact or misinformation?

Horse puckey.... 

intact audio makes a reasonable point. I doubt most modern cart's have limited vertical compliance tho.  I think i would be more concerned with the reverse, since in the old days the grooves were cut entirely laterally (well, there was that 45 degrees but the two were out of phase....) so the reverse is more, IMO, likely- except that about 0.01% of us have mono cartridges.

Yes, a buddy of mine does. He also has multiple arms on one table. Wonderfully insane.

No. I agree with all the other members that no harm will occur. I also use my mono switch with an old LP. It is sometimes amazing with a stereo cartridge. 

I don't know about everyone else. I have thousands of records and maybe 30 mono ones mostly old Jazz. Spending Thousands of dollars to get a mono cartridge as good as the stereo one for 30 records seem a bit odd almost as bad as buying a reel to reel to play the 30 or so prerecorded tapes that exist.
