I was rabbitholeing physics videos and came across vacuum boiling water. Could we safely vacuum boil gasoline, I wonder?

They say that the fuel "atomized" when it is injected into the cylinder but that is obviously a misnomer, as it's more like misted, like a windex shot. "Molecularized" would be more proper but the fuel is still in liquid form anyway so whatever.

I'm sure gasoline fume is what actually burns so just pumping that into the engine instead of liquid would drop the consumption without losing horsepower, I think.

Sounds dangerous but with the right measures in place I think it could work, maybe with a carburetor instead of direct injection.

Thoughts?

You're correct. Others have explained why.

Now I would like to run an engine on ethyl alcohol.

That's much more doable in a modern engine. You'll have problems with the water content, especially in cold weather. You'll also lose quite a bit of the engine's rated output. This will require a free fuel source (wood, waste oil, dried jews, etc) to distill the alcohol. There are a few methods to dry the alcohol, but I can't imagine doing that on a large scale myself.

Sweet I've got all the dried jews in my basement. Knew they'd come in handy someday

Yes, and even if you run several modern distillers 24/7, you'll likely never burn through all 6 million of them.
