i think the 'problem' there is that in a global market you have products that you would never have access to otherwise...
would the local market sell an $80 dac? what would the markup be? if the internet didnt exist you wouldnt have access to this stuff
i literally have two stores in driving distance that sells "hi-fi gear" but its all surround gear... and any dac is something like a $2,000 NAD
ok we all know that places like shenzen and hifiexpress and that say they have 2 yrs warranty but have you tried exercising that? good luck
in my market its basically accept an $80 dac from shenzen audio or aliexpress or.... nothing
its easy to parrot "buy local" but really there's no one here who makes this stuff, and there's no one where who sells this stuff... and so the lack of warranty is easy to accept is your alternative is to "starve" so to speak
