I think buyer etiquette is much looser than seller etiquette just because of the difference in what each side is asking of the other.

If you're a seller, you're asking the buyer to give you money, and presumably to travel to a location of your choosing to complete the transaction. You should be more responsive because you're the one hoping to get paid. I had a FB Marketplace thing a few weeks ago where I offered to come by to pay someone their asking price three different times and each time got the "sorry I didn't see this, can you come by tomorrow instead", rinse and repeat. That's bull####.

If you're the buyer, anything you've done that requires seller to make a real effort or rearrange their day you have to come through on, or give reasonable communication if not. For example, if you want to come see the item and you give a time that you're going to swing by to look at it, you either need to show up or tell them well in advance that you've changed your mind.

But in terms of asking a question and then ghosting after the answer? No big; as a seller I have put forward no real effort by typing out an answer to your question, it hasn't inconvenienced me. I just assume if you don't follow up that you're either no longer interested or the answer led you to the conclusion that what I'm selling isn't what you want.
