If I consume a good or service then I’m a consumer, whether I had to pay for that good/service or not. As a consumer, it is in my interest that I can look up the name of the good or service and not have confusion as to which good/service I’m obtaining.

Yep. And if someone uses OPs mark on or in connection with goods and/or services in a manner that is likely to cause confusion, deception, or mistake about the source of the goods and/or services, then they have the right to sue them.

I don't think that's happened though.

But you don't get those protections or ability to sue if your trademark gets rejected, which is the problem here.

I don't know about the EU, but in the US a registered mark only gives you the presumption that's valid. But those presumptions can be challenged in court.

Of course, if you can't prove to the examiners that you even have a right to the mark, you're probably gonna have one snowball's chance in hell of a time proving that someone else's use of it is invalid in court.
