Whats the point of Wifi if you need to power it with a USB cable? It should come with a buck-boost so we can run it with batteries! (at least for that price)

I'm just guessing here, but maybe so that you can power it with just a common USB powerbank, and that way it's much more accessible to a wider audience?

That is starting to require too many resources... We want this things to consume as little as possible.

What do you mean? Tons of IoT devices are powered from mains, not batteries.

Tons on IOT devices? Could you mention a few (that are actually useful)? The only one I know is the cellphone.

And even if they were powered from mains I don't want it to be inefficient. If they don't come with a buck converter with low quiescent current please don't buy it.

Deep sleep is 7uA, 240uA light sleep.

And there still is a Vin to power it how ever you want, takes 6-21v. And a USB port makes serial easy.
