"It is very difficult to prevent anyone from selling sex through criminal law. Criminalisation can make it more dangerous, but there is little the state can do to physically curtail a person's capacity to sell or trade sex. Thus, prostitution is an abiding strategy for survival for those who have nothing - no training, qualifications, or equipment. There are almost no prerequisites for heading out to the streets and waiting for a client. Survival sex work may be dangerous, cold, and frightening- but for people whose other options are worse (hunger, homelessness, drug withdrawal) it's there as a last resort: the "safety net" onto which almost any destitute person can fall. This explains the indomitable resilience of sex work."
