Explanation:

Gladiators were slaves that were owned by the members of upper class society in Italy.. The reason they fought was because the champions among those gladiators tend to received fame and glory in the community and obtain a chance to obtain their freedom.

Because of this, Gladiators were not allowed to own private properties or freely roaming around the street.

Gladiators lived in barracks. Unlike normal houses, Barracks consisted of training / workout equipment's that the gladiators can use to prepare themselves for future fight.  The owners of the gladiators were usually the one that control their diet regimen along with providing trainers for the gladiators.

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
