alt Hacker News>If gyms faced a situation where people would go and spend 18 hours working out every day for a month, they would probably change how they billed things.
Not the best example. The upkeep cost of a gym is pretty flat regardless of how much people use the facilities. Two people can't use a single machine at the same time make it wear out twice as fast. The price of memberships is not correlated to usage, it's inversely correlated to the number of memberships sold.

The machine doesn't care about the number of people using it. If it's constantly being used, it will wear out faster. You are conflating "we price based on expected under-utilization" with "costs don't scale with usage." Those are different things.
The inverse correlation you talk about isn't relevant here - People buy gym memberships intending to go, feel good about the intention, and then don't follow through. The business model is built on that gap. That's pretty specific to fitness and a handful of similar industries where aspiration drives purchase.
Anthropic doesn't sell based on a "golly gee I hope people dont use this" gap - they sell compute. Different business.
Two people can't use a machine at the same time is the issue. If you have 50 machines and 200 customers all of whom want to be in the gym 18 hours per day that's quickly going to lead to cancelled subscriptions. Now you need more space and machines or some other way to balance things.
