This is probably a dumb question, but if I run a wire around the
perimeter of my house along the eaves so that it is as high as I can
put it, is that dangerous with regard to lightning?

Repeat after me:
We always disconnect external antennas from radios when we are not listening
to them, and especially when thunder storms are in the forecast.

Static can build-up in the wire from different sources. It's also a good
argument for having a transformer (at least 1:1) in your feed line that
provides a direct path to ground, in addition to your lightning arrester.

It can also be influenced by your tolerance for risk. If you don't like
rolling dice, then lightning protection, a transformer with a direct path to
ground and diligently disconnecting the feed line are all advisable.

Where does one find such a transformer? Why does it need to be at
least 1:1? What does that mean?

I use a Palomar MLB-1. A 9:1 autotransformer which provides
sufficient impedance reduction to facilitate the use of Coaxial cable.
