Is There a Product That Does Not Have a Viral Loop?

Is there a product that does not have this viral loop or is it possible to always implement a viral loop with any product you build? I don't think so. It's something that it came right in the nature of the product itself, right? Not... I don't Think any product can do this. For example, if you create a referral program, right? Right. That is also something like a viral loop too, but it's like a very weak loop. When you use the product, you don't have a natural action to refer other people. You only refer to other people when you want to make money,. But if you don't, you just want to use the product
