If you make categories by law and afford certain benefits to those categories then people will continue to adopt them and perpetuate it. Caste is complex, build over many generations. It is however very easy to destroy by just forgetting the things people use to categorize others and would be nearly impossible to rebuilt in the modern world as it was a system built for local communities where people intimately knew each other for generations. The goal should be breaking and forgetting knowledge that let’s people distinguish castes in the first place. Shoplifting is shoplifting. No one is going to “forget” you can steal things so you need explicit laws forbidding it in perpetuity.
