It's hard to find newer movies on laserdisc, vhs, or home film projection, so analog is out.
I buy or rent media from online services occassionaly. Much content I would like to watch isn't on subscription platforms, or is sometimes on streaming platforms I don't want to use. Some content isn't available to rent, and some content I feel like I'm likely to watch more than once. I prefer to buy discs, but some discs are difficult to obtain and sometimes I don't want to wait. When the buy price isn't much more than the rent price, I consider it. Or if I have amazon credits to use.
