The word "eroticism" in this article is quite misplaced. A fleeting sexual thought about a stranger who happens to be providing a service to you in that moment (hair brushing, apparently) has nothing to do with eroticism, precisely because it's not "sexualizing" in any real-world sense. Incidentally, eroticism properly understood (i.e. turning actual consensual love, intimacy and perhaps even sexuality itself into a genuine, positive and human-affirming artform) is also quite dead, but not for any reasons this article is talking about. It's just getting caught in a cross-fire between the most disrespectful and lewdest sort of commercial hardcore pr0n and a kind of renewed, reactive prudery from governments and policy-makers.

She means being horny and being open about it, but the word "erotic" sort of has lost its meaning as you are saying, yes.

>A fleeting sexual thought about a stranger who happens to be providing a service to you in that moment (hair brushing, apparently) has nothing to do with eroticism

I argue that's eroticism in its purest form.

>a quality that causes sexual feelings, as well as a philosophical contemplation concerning the aesthetics of sexual desire, sensuality, and romantic love.

both subjects don't need to be purposefully sexualizing for an erotic event to happen. That's a bit of what powers some of the more out there fetishes (like say, having your feet massaged, which has nerve connections to many more part of the body than one expects). It can escalate to something sexual, but most adult humans tend to learn how to suppress such desires, no different than not buying that candy at the store or hot wanting to slap Bob at work when he talks about the latest conspiracy theory.

I guess so. The US has been so screwed on sexuality for decades that there's no one true meaning anymore. Which isn't bad, but when you range from "a person looked pretty" to "Onlyfans DM's" your word may indeed lose meaning.

It's interestingly enough a global issue too, in terms of policy. But unfortunately it's pretty low priority compared to the rest of everything else going on.
