I do not listen to records at home. 100% digital, and usually in my home studio/offices. I only buy physical releases in a few cases.
1. I have a friend in the band, or who runs the label, and will buy it to support them (OR, it is one of my favorite bands...). This can happen online or at shows. I love getting the LP at a record release show... Ofttimes get it signed...
2. I really enjoyed a band's set. Sometimes I just buy a t-shirt, but I have over 140 band t-shirts, so sometimes I will instead grab a tape or a 7 inch or LP or CD to support them (or a pin/button or a poster or a patch). But I am trying to buy less t-shirts, and physical music releases, and am trying to focus on posters at the moment.
3. Record Store Day (and Cassette Store Day) are the day (s) I go to my local record store, and support them.
