What like a deal to sell dangerous drugs to teenagers, or a deal to market child pornography, or a deal to provide trafficked slave labour to an employer? You wouldn't want the government to get involved in any of that through the legislative process?
Well who exactly determines what is "right" in that case?
As a democrat, in a parliamentary democracy, who believes in that system, I accept the rule of law, and don't pick and choose those laws which appeal to me or my own personal prejudices as being the ones to abide by.
The (UK) law is clear about what you can and can't do in this respect, if you are selling goods or services to members of the public
