You could, but it misunderstands luxury marketing.
The difference between "luxury" marketing and even "premium" (or mainstream) marketing are the former's efforts to influence people who are never going to buy or use the product.
A lot of a luxury good's status comes from the "halo" given to it by all of us who'll unlikely use it - thus giving it the allure to the people who have the money.
So, in essence, it's more important for a luxury brand to have mass market penetration, than it is for a premium product.
For example, Aston Martin needs you to know it's an unattainable symbolic brand, and does that through mainstream marketing (like Bond product placements, YouTuber videos etc...) more than BMW does (who're selling to a premium audience who will buy on product rather than perception).
TL;DR: perversely, it's in everyone's interests to use influencers more for the luxury industry than the rest of the industry, and why it's seeing the abuse it is.
