But that’s just it; it’s not a zero-sum game.
Let in 5 buddies on your gym membership, even individually vs as a group, and they’re using up finite resources. They’re using the machines, tossing towels in the laundry, using water for showers (I’d hope), and just in general taking up space in a limited/finite setting.
And what happened with Netflix’s “sharing is caring” where they encouraged password sharing even for adult kids away at college, and other “friends”. Now, they want to “crack down” on password-sharing. They’re pulling a Matallica. I literally don’t know anyone who got “cracked down” on and ended up buying their own Netflix subscription. Not saying it doesn’t happen, but I doubt it’s as frequently as they hoped it’d be.
But as I mentioned, it really doesn’t affect anyone if I take my sister’s shopping-list and pick up what she needs, as her proxy, or just hand off my card (if I had one) to her to do her own shopping. She’d be unlikely to buy a membership if I stopped doing that, as she just buys from Home Direct or whatever.
Maybe people do intentionally share a single membership, whether it’s Netflix or Costco. Take away the sharing, and it might not be worth hanging on to, even the main purchaser. So instead of having 1 now, and getting 2 or more subscriptions after any “crackdown”, then end up with 0 instead.
Ages and ages ago, I was in on one of those “gas club” dealies, where you buy in and get a card which allows X off each gallon of gas at “participating stations”. It paid as long as the membership cost was shared, as the local Gasatorium was a bit more expensive than the Sunoco down the street, and getting 10% off would only pay if you used a decent amount of gas and the membership wasn’t too pricey. So share with 3 other people/cars, and the membership cost is quartered.
They then required linking the membership to A license plate. So if you had 2 cars, you had to buy 2 memberships. We dropped out, and less than 2 years later the program collapsed.
Funny thing is, before the restriction, I was heading home with a cow-orker who needed to gas up, I got off the expressway first but he’d continue on, so I told him to follow me in. The guy at the gas station even held the nozzle while cow-orker for 20bux worth and handed me a 20, and I topped off in my car the rest of the way.
So it wasn’t that gas stations were balking at people “sharing” memberships, as they sold more gas. It must’ve been those running the program getting greedy and wanting more memberships.
