Legalizing prostitution will make it super easy to cover crimes up under the pretense of "legality". Statistics won't show you what is happening behind the scenes.
There is distinction between legalization and de-criminalisation.
The purpose of making anything legal is to regulate it - laying down what's allowed, when allowed and what's not with punishment if violated.
Legality is also essential to ensure rights of all stakeholders involved are preserved in this case - rights of sex workers violation of which gives them the right to approach the courts or government - a door which remains closed when something is not recognised by law.
Also, more rights are violated and crimes happen in unorganised market or unregulated market as there are no checks and balances. There are no Grievance redressal mechanism for victims involved. No rights protected by law.
With that being said, the topic is debatable as both sides have some merits so I won't comment on it further
