I don't see the difference between cost and viability. Of course we can fuse atoms. We've been doing it with regularity since the 50s. Of course we can use magnetic confinement to do it. The only reason we haven't burned a plasma in a magnetic confinement machine is because the machine to do it costs a lot of money. We don't have the industrial throughput as a society to make 1,000 megaprojects simultaneously. Whether you call that a cost problem or a viability problem is irrelevant.
