While waiting for a better network in every part of globe, we do need local power like you described. But, none of your examples couldn't be implemented remotely, and be more powerful if implemented remotely. We have all the tech to have faster and better bandwidth, it's just a financial implementation problem (i.e. 'some dudes need to have their bank accounts happy' kind of problem).
