We could start using Mrr. for that (pronounced “misterer”).

Going from Master to Mister does feel like a downgrade

"Ms" didn't just happen, it was an effort. Those dudes should be the change they want to see in the world.

Maybe they can start by taking their wives' last names xD

Some do.

I offered, but my wife was like "hell no"! So I offered that we create a new last name instead of using either. She declined that as well.

I wanted to give our kids hyphenated names, with both my wife's surname and mine.

She insisted they get my surname only. So that's what they have.

Many cultures the last (and first) names differ by the gender of the name holder, so it makes it even more confusing if you try that.

Notably, both my (now ex) wives insisted on taking my last name. I didn’t really care either way.

You can get a PhD and have a title change to Dr!

You can also buy a parcel of land in Scotland and be addressed Lord.

IIRC that's not really true and basically just made up by a company that sells souvenir land plots in Scotland

Then you’ll trigger the “it’s not appropriate for PhDs to use the title Dr outside of academia” people

That, in turn, will trigger the "Dr Jill Biden" people
