Trademarks are the most important kind of intellectual property law, not for the owners of the trademark, but for the public. It protects you from shoddy fakes that do stuff like install malware (which other counterfeiters might have tried if the law were more lax on counterfeits) or stuff not following safety guidelines (like fake chargers that burn your house down). Well enforced trademark law means that you as a buyer can investigate a seller and know what you're getting based on their reputation. And well enforced trademark law means that you as a seller are incentivized to protect your brand by making good/safe products. EDIT: you can argue copyright or patents are bad, but fundamentally I cannot see the world be a better place without trademark laws in some form.
