Looking at the name of the company, reading recent reviews, and ensuring there is a non-obviously-fake address associated with the business doesn't sound like a tedious list of hoops to jump through to me. You should do all this stuff on any marketplace, Amazon or elsewhere.
Honestly, if we're talking about convenience, Amazon is pretty much the best game in town. They have many documented failings and faults, but being inconvenient isn't one of them.
if Amazon just wants to be the market, that's one thing. but they're also trying to position themselves as a brand name with notion of value attached (e.g. amazon basics).
I value my time and don't want a 'caveat emptor' market experience, so I've largely given up on Amazon as a reliable market browser.
