That's why you tax it. The benefits of taxing vices and other negative externalities like single-use plastic items is multifaceted: the consumer will start to think twice about the added cost, the firm providing the item is incentivized to look at alternative methods, and the government gets additional tax revenue (that ideally goes toward the damage that the item does to society/environment/etc). It's not the state's job to tell me what I can and cannot do. They should, however, nudge me toward what they'd prefer.
