Most of humanity has lived without police for most of its existence. It's not an inherent part of life. And in many places, the police is a very recent (few centuries old) invention with ties to oppressive structures such as slavery and colonialism.

Whether abolishing the police, or defunding the police (to deescalate the militarization), both are proposals formulated by serious academics and politicians, whether you agree or not. It's not virtue signalling. If anything, "defund the police" is still very badly regarded outside very small circles and there's no credit to be gained by holding such positions.
