You are totally missing the point here. Our mum taught us to use things under glasses when used on wooden furniture. That is not the case with other things. If you leave a book on that surface it won't leave a mark. Same for other items. So, Homepod doesn't strike people like that kind of product that needs something underneath it and that is the whole issue here. So your picture is a miss and I'm sure you know that by now.
Did your mum teach you how to take care of oil or wax finished furniture? Is this something you buy? Most people who buy high quality furniture make the effort to learn how to maintain it, and take steps to protect it. This issue does not occur with that table you just bought at IKEA.
