You’re right that this has been a big reason for this resistance. It is not only that controlling the means of supply drives long term profits, but that the supply infrastructure generates huge profits as well. The largest portion of your home electricity cost is not the production but the delivery. If we could free everyone from both these costs almost everyone would be a lot happier.

You should extend this way of looking at it to the rest of the capitalist system we are being subjected to. Poorer quality goods lead to higher repurchase rates and more waste. Company mergers stifle new technology and slow human progress. These systems need heavy regulation and even extermination.
