Anyway, welcome to BF.

The C&V guys get bent out of shape because it's usually a vintage frame that gets this treatment. We lose lots of classic frames this way. If you decide to do one, don't hack off the braze-ons, and save the original components. If you paint it, take a picture of the original decals so maybe someday in the future it can be returned to it's former glory.

As far as why? Single speed and fixie riding is fun. It's also a great supplemental training tool. And you'd be amazed what you can do with one cog. And it can be cheap, although I have too much $ in my gold one below.
