AKA the vapourware approach.

The problem with that is that you're burning goodwill before you even launch.

People land on the page, click BUY, get told that it doesn't exist yet, and spread the word that you're selling vapourware. The next time you have an actual good idea, you'll have no takers.

But you aren't actually taking peoples money, if you were, I agree you burn bridges and get a bad reputation, however it's very easy to rebrand and I'm not suggesting to do that for thousands of customers just enough to decide if it's worth building or not.
