My library of Blu-Rays is over 700 at this point, about 165 of which are 4k (Including Top Gun: Maverick, which is on for tonight)
I continue to own and build a physical library for all the reasons you mentioned. On a good TV with a good sound system streaming just cannot match the experience.
Sadly the U.S. is backing away from physical media, so I find myself buying both used and imports more often these days. Fortunately, Asia & Europe still seem to be interested in the format.
