You have learned that the fewer substitutes an item has, the more price inelastic the item is, and that this gives sellers some leeway in raising the price of the item. It follows, therefore, that products that are addictive can be sold for higher prices.

Think critically about the items, including media and social media, that you regularly consume. Are designers and manufacturers incorporating features into those items to "addict" you? Have you ever actually considered whether or not you have control over your use of these products? Does this concern you?
