What are some good things about an animal circus?

i can onlt think of a couple good things but apart from that i think animals should be let free

1: They get treatment if needed

2: Some circus people use other techniqes to train animals instead of using violent methods , they bond with the animals

3: The government havent stopped it so it cant be that bad to some people

4: Entertinment

5 : traditional

But personally i have a million reasons why animals shouldn't be in the circus i believe that animals she be let free.
