The laws re: brothels do make this appear like a partial decriminalization effort. For instance, operating an unlicensed brothel only causes you to incur a $10k fine rather than prison time. The same with health violations, where "not promoting safer sex practices" i.e. using condoms in sex acts, is a fine-able offense.

This is no different from any other business. You can be fined for operating a hairdressing salon without a license. This doesn't mean we've "partially decriminalised" hairdressing.
