The problem is not whether I "need" them. No-one "needs" them - they're more convenient, they provide a better service in the short term, that's why they are winning.

The problem is that a massive company essentially owns online commerce, anti-trust legislation should be addressing this and somehow it's not. Let them own a few % of the market, don't let them literally take over.

I'm in Germany, so I quickly googled for some stats on Amazon's market share. [1] In Q2 2019, their biggest market share is in electronics at 24%, with toys/sports at 18% and books at 15%. Everything else is 6-10%.

I understand your concern, but the reason that anti-trust legislation is not addressing this is that there is frankly no monopoly here.

In the UK they have 30%, followed by eBay and the major supermarkets, so basically ~3 companies own half of online commerce.

The current percentage is almost irrelevant anyway, the endgame of this is monopoly whether or not they have it right now, the vertical integration of delivery alone is enough.

I'd split up the major supermarkets as well FWIW, but that's a different discussion.
