When businesses charge customers for bags issued, you may think 5 or 10 cents per bag expensive. But what you don't see are costs of bags are included in the prices of goods presently and cashiers issue bags wastefully (so you pay more for bags). When costs of bags are not inculded in the prices of goods, businesses would probably adjust the prices of goods lower -- may not for all goods but some goods.
For example, a supermarket charges 10 cents for a big bag. Presently you pay 3 cents for the cost of a bag which is included in the prices. You may pay average another 2 cents for wasteful issuing of bags. If the shop adjusted prices due to costs of bags are not included in the prices of goods, you could pay average 3 cents less for a goods. While you would pay 10 cents for a bag, but actually you would just pay 2 cents (10 - 3 - 2 - 3 = 2 cents) more than what you have been paying now for a bag. If you don't accept a bag issued, you would gain 8 cents. This would be a choice you don't have presently. Therefore you would actually pay not much more than what you have been paying presently for bags issued and you could save some money if you don't accept bags issued.
The purpose of businesses is to sell their goods. They would like to convenient their customers by giving them bags to carry what they buy. So it wouldn't be their intention to profiteer from charging customers for bags issued. They earn more by selling their goods.
The new way would reduce the number of bags used and so it is good to the environment.
