Arbitrary notions of safety and conduct. People know how they should conduct themselves, and those who will do something wrong don't care.

Arbitrary notions of power. Does enacting this over the members of this community improve anything? No. There are no issues within it to begin with. Nobody is rampantly "pissing in the pool" on a daily basis, hell even monthly basis at that.

Arbitrary notions of acknowledgment. Do you read through every ToS you've agreed to? No.
