Any reason not to buy Amazon stock?

I can’t think of any reasons to not buy and hold AMZN long term. I’m planning on dumping 100k into it as it goes from $86 and under. AWS has double digit growth, they’re constantly reinvesting into the business to grow more. E-commerce will weather well in a recession as everyone buys online. Even if economy declines, long term Amazon will be the dominant e-commerce site. They are pretty much a monopoly with competitors like eBay and ETSY only serving small niches.

What’s the bad side of Amazon? Something that could jeopardize it’s longtime success? $Amazon (AMZN.US)$
