I don't. I need more chargers than devices for the reasons already mentioned. The only way I could obtain the surplus was by buying extra chargers.

In other words, the problem is not that the charger was included with every device you boy.
The problem is that
a) you buy devices too frequently;
b) when you get a new one, you get rid of the old one in such a way that you keep the charger.

Mosen is right, people's habits need to change.

If you have too many, why don't you donate the surplus to a charity, for example? Not all charities accept electrical goods because then need to be safety tested which costs them money but some do. I purchased the extra chargers I mentioned above from one such charity shop.

Correct in theory. In practice, as we saw with the Jolla tablet, the price is set and excluding components is a cost saving exercise.
