100%.
We've not needed 100watters since the 90s and the advent of decent PAs in venues. But it isn't about need. Big amps are a culture too.
I sometimes wonder if the doom / sludge revival in the 2010s was partially down to the fact that big old amps suddenly became super cheap. I know loads of mindbendingly heavy bands who wouldn't have a sound if they weren't able to pick up cheap old Laneys for chips prices.
You can absolutely list stuff as collection only on Reverb.
I do think the "people don't want big amps anymore" is a bit overplayed as an excuse for offering a pittance for decent quality gear. Sure there are more practical solutions for most of us, and digital tech has come a long way, but the experience of Marshall stack on 10 will always be the foundation of a whole swathe of music history that can be approximated but not recreated without the real thing.
I wonder how long it will be before industry infuencers start bemoaning the feel and depth of frequency that was lost in the big amp cull of the oughties and the prices start coming up again. I'd hang on to it if I were you.
