OP- I think you ask a really interesting question!
I have a few very expensive bags. I buy them because I want to treat myself and I think they’re gorgeous.
however, I’d be lying if I didn’t admit I was buying into the design/ brand and the status it confers.
you are right- if you are paying more than a couple of hundred quid for a bag, then you are paying for advertising/marketing/ label. (though maybe also design to a certain extent)
like all fashion- this has its pros and cons. Yes, it’s completely harmless to want to buy into luxury/ feel good about yourself, but it’s also marketing at your insecurities- people want to look successful/ refined/ Sophisticated.
and of course many people then judge others on their material possessions.
no different from flash cars.
it’s a status thing- many women will notice your bag. Blokes don’t care.
anyone saying it’s only because it’s better quality/ they can afford it, isn’t really answering the question.
going purely on logic, you only ‘need’ a couple of bags( different sizes for different situations ) anything more is technically a waste of Money unless it fulfils another need.
I can afford all the top of the range DIY tools B&Q can offer- doesn’t mean I buy them!!
