I bought this "senior" plant two years ago and, not having any experience with Argyroderma in general and senior plants in particular, I've been worried about it ever since. Looks like it was not necessary. The plant is just doing its thing with very little support.
The roots tend to dry off as soon as the substrate is dry. The plant seems to barely cling on to anything. It feels like it sits completely loose in the container. It doesn't ask for water much. And so, every time I actually need to water it, I worry the roots won't "wake up". They always do. Probably because fine roots grow just as quickly as they wither. I was worried the bulk of old leaves would start to rot but being located overground and on top of pumice, there's no sign of it. At one point I thought one of the heads will die off. This was also unfounded.
All in all, this plant seemed like a trouble maker but it really isn't. It's a pretty laid back kind of plant as the below quotes will demonstrate.
"She is watering me again. Doesn't she know I don't need it now? It's okay human, you'll learn."
"Bad weather? No sunlight? Never mind, I'll just nap a little longer."
"You think my roots are not good? My roots are just fine and completely enough for what I need, thank you. Worry about your own roots."
"Human stop fussing. You made my beard wet. I know you didn't mean to. It'll dry."
"So, you've accidentally pulled me out of my bed for the tenth time. Can't you just let me sleep?.... No, my roots are fine. Go away."
