Problems that don't happen with actually good clothes.
If you buy from (It's mostly menswear brands here, sorry ladies) companies who specialize in actually quality vs "fake exclusivity", trends, or hype, than you'll never have to worry about this.
I'm specifically talking about selvedge denim brands (i.e. brave star, naked and famous, the osaka 5 brands, etc) high end leather makers (i.e. Horween, Shinki, and the people who make stuff with them like Schott), goodyear welted boots/shoes (i.e. Whites, Nicks, Grant Stone, Meermin, etc), high end made in the USA brands (i.e. Gustin) - this will literally never happen. It's far too damaging for them to destroy any kinds of their stock given it's natural exclusivity and the fact that they always sell basically everything they've got.
The fact that they had to pass this ban at all is a signal that normies are bad at buying clothes, and they should feel really bad about it too.
