Why it makes sense to progress away from school uniforms.
If you don't want any opposition towards the government body then remove opportunity.
Following the theoretical adage of Murphy's Law, "Anything that can go wrong will", you can conclude with opportunity comes fulfillment and the seizure of said opportunity. When an opportunity can be seized, it could and has more chances of happening than not. Such as when the roman government had the chance to fall, it did, and when the symbolic twin towers had the chance to be destroyed, they did. As soon as an opportunity opens, that opportunity becomes an option, a choice. A choice able to be made by the conscious mind.
If you, however, abolish that opportunity, the option of seizing said opportunity is also removed.
Removal of opportunity gives no reason to oppose rules.
