It saves you hours elsewhere.

No impact on a central repository even when you tried some complex merge
and got it wrong.  Nobody gets to see your damaged foot.  You just
messed up your personal sandbox temporarily.

That sounds like "nobody will ever need a car, because people ride
horses quite differently than they would ride a car".

Do we really need cars?  I think not.

I've been the designated merger for diverging feature branches at the
last company I worked with.  Because I was used to working with git.
The VCS at the company was Subversion.  Subversion is quite better with
regard to merging than CVS ever was.  Still I was able to do this stuff
quite more thoroughly and faster with git.  And with "faster" I mean the
investment of human time, not computing time.

That's the sort of sentence in software development environments that
sets off all my alarms.

"Stay with our stuff, it is slated to get better.  The stuff that works
better is bad for you" has quite rarely made good on its promises in my
experience.
