Facilitating crime is only a bad thing if the crimes are bad.
Billions of people in the world live under oppressive monetary regimes, with governments forcing people to save and spend in a local currency that the government devalues overnight (Zimbabwe, Egypt, Nigeria). Transacting in USD or some other stable currency is illegal. Bitcoin allows them a way out, as it's permissionless and hard to stop. These people using Bitcoin are able to prevent their government from stealing their savings.
As for illegal drugs, consider mifepristone. This drug is unavailable to women in many places, including 52 of the 54 countries in Africa and in some parts of the US. Purchasing and selling are illegal, but the transaction can happen when facilitated by a method of payment without a gatekeeper. These women using Bitcoin are able to take back control of their bodies.
Starting three years ago, young Russian men were forced into taking up arms and shooting Ukrainians. Those that fled Russia were limited (either by law or by "enhanced pat downs") in how much money they could bring with them. Western sanctioned restricted accessing their Russian bank accounts outside of Russia. But by converting those rubles to Bitcoin, the money becomes accessible anywhere, and is unconscionable by border control. These men are using Bitcoin to avoid committing violence.
