Those are good reasons. To add to that:

1) Companies are still paying for office space right now, even though people aren't using it. If they reduce their physical spaces in the future, the capital will likely go into hiring more people, which I'd rather see.

2) It's tricky from an accounting perspective, though I like the one-time stipend idea mentioned in the comments here.

3) Not having a commute saves time AND a lot of money, I've personally spent a few hundred dollars upgrading my desk / accessories to get comfy, but saved many times that on commuting and misc expenses.

4) Adding to the above, there are many things that companies generally aren't expected to pay for, like wardrobe, transportation, food, cell phone, etc. It seems like home office falls into that bucket as well based on precedent. Maybe that will change, but I don't have any expectations that it will.
