I'm assuming you are being facetious in order to highlight an alleged absurdity of the suggestion. Though in reality the suggestion seems quite sensible to me.

Where I am, we've been under the effect of a pretty steep tax on plastic grocery bags that get noticeably passed along to the consumer. The result, from my personal experience, seems to have been a widespread adoption of tote bags. These last a very long time, 5+ years in my own experience. It has not resulted in a decrease in supermarket visits, to the best of my knowledge.

Or perhaps I'm misunderstanding your comment.

I can walk to the grocery store, now I will have to drive to a bigger store because I have to buy everything in bulk.

Your fine isn't tied to any externality so it is stupid.
