It isn't blank. You get a preview-shaped white box that says "No preview available"
As stated above, my site's previews show a blank (white) space with nothing in it.
the question is how your ordinary human would react to this
My question would be "what percentage of searchers even look at Google's previews?".
I haven't seen any official figures, but it seems to be a minority interest.
the site itself had said Nuh-uh, keep your nasty previewbot offa my land.
My site is actually saying "I wish to opt out of previews while retaining text snippets".
Which, of course, is what this thread is about.
