I haven't suggested that.
Let me see now
We sell alcohol, which is harmful and addictive, in premises, and supervised by people, who have been approved and licenced for that purpose, and under legal control, at controlled times, and to people of qualified age, and who are not intoxicated. If they breach the conditions of that licence, it can be revoked and they can go out of business. The strength of the substances they sell is controlled, and it is not permitted to be adulterated with harmful substances. The premises can be inspected at any time, the vendor must be able to prove that they acquired the products legally, tax paid, and test purchases are made to verify that under-age people are not supplied. Tax is paid on the businesses profits, and the wages of the staff, and on the alcohol sold.
Are you suggesting that it would be better to sell alcohol down dark alleys, by unknown people, with no regulation and control, without paying tax, where the profits feed international organised crime, when the strength and purity of the substance is unknown and uncontrolled, and a child can buy it as easily as an adult?
