Edit: I've seen this at least in NY, Florida, California
I've read that you can't move chairs, etc, either. I understand it's part of the contracts between venues and unions.

IIRC, Australia requires an electrician for even this sort of minor work.
That likely depends on local codes; not sure about light fixtures specifically, but I definitely have encountered variations in different cities in the same county when it comes to ceiling fans.
Those laws (especially when combined with licensing requirements that exclude all but those who have a full time career in that field) are a massive hindrance to individuals and many businesses. They usually amount to little more than a potential transfer of liability. If your house burns down maybe you can try to point the finger at the licensed professional (good luck at that). The only thing it accomplishes is making it (slightly) harder for people who are habitually grossly negligent to keep working in that field. This is a non-benefit IMO because so much business is based on reputation anyway. The downside is that by artificially raising the minimum price access to access skilled labor you cause all sorts of work to be forgone because people can't afford it.
Plenty of house fires have been started by people who couldn't afford to pay an electrician but could afford an extension cord.
Edit: Since I'm apparently so wrong does anyone want to explain why. A down-vote without a reply is roughly synonymous with "your opinion is inconvenient to me but I cannot refute it"
...is using the downvote correctly. Downvoting is for comments that are not productive contributions to the kind of discussion desired on HN, responding to any post that merits a downvote is increasing the noise-to-signal ratio.
