I reckon there should be a development and engineering team formed to research on Asic resistance. Users should be given back the ability to mine in the privacy of their own homes where the government has no right to stop them.
Inasmuch that I agree with your suggestion on the development of energy efficient Bitcoin miners that can operate within homes, I don't think that will stop the government from its persistent attack on Bitcoin.
The major weakness of Bitcoin is not how it is mined but that it has a strong adversary called centralised governments that want to control every aspect of our lives.
Bitcoin has survived this attacks for years and hopefully someday the government will give up and accept that Bitcoin is a part of people's private live.
