Why IT companies don't hire remote programmers?

From company's point of view I can't think of any advantages of forcing programmers come to office every day. Why is this style of working so unpopular between employers?

Here is a short list of advantages:

Meetings, brainstorms can be done remotely - and very often are. Many companie already work remotely.

There are less distractions when you work from home.

Your boss knows _exactly_ what you achieved by looking at your commits.

Contrary to common belief, knowledge and new ideas spread quicker in a team. Think of common chat window vs water tank herding.

Some companies say that remote jobs are threat to their security. In 99% of cases this is not true (VPN anyone?)

Some people say that meeting in person every day on a lunch is very important. I am saying, bitch please, I won't do my job any better if I have pizza with you on a regular basis.

Some bosses _need_ to see you in the office otherwise they feel uneasy and lose sense of control over a team. This is both funny and sad..
