Your argument is similar to the “it costs less than a cup of coffee” subscription defence, and just as flawed. Not everyone drinks coffee or goes to restaurants, and the prices and experience of restaurants and coffee aren’t the same around the world. Don’t try to make comparisons between digital and physical purchases with no analogue.
If I go to a restaurant I can pay cash or do it securely with a card. If I don’t like it, I’m free to never return and not think about it again. When I pay for a subscription, unless it’s via the App Store’s in-app purchases I’m giving you a name and credit card number, and have to remember to cancel it if I don’t like it, but even if I do I have to trust you with the information I already gave, or send an erasure request then trust you’ll honour it, and, and, and.
It’s a fundamentally different experience. No, you don’t go to a restaurant and ask for free bites, but after visiting a restaurant you don’t have to spend months fighting them to stop sending spam, or worrying that they charge you again even if you didn’t eat there, or worry they’re selling your data to other unscrupulous companies, or, or, or.
It’s not about the cost. Your subscription could be $0.01 a year and it would still demand more trust than a restaurant.
