This may not be you, but the people who have said that to me irl walk significantly less than I do. And saying these things to people who don't yet exercise can make them far less likely to start as it's a far bigger step to do so. Podcasts and recorded lectures are what got me exercising in the first place, because I was excited to hear the next part. I now only have headprones on some of my walks, but the gateway drug of entertainment was a very useful stepping stone. And still often better than sitting at a desk.
