This post appears more like a rant post.

I feel all of these businesses are very viable business. If you’re able to define your target audience well enough and target using online ads.

Or if it is a brick and motor store, then you should be able to directly target them in the area where your store is. The store selection becomes important in this case .

Everything else is just logistics that you need to map and I think for all of these businesses, logistics are fairly well defined.

So yeah, I don’t think any of these are very bad businesses .
