It's not dishonest to portray it as fundamentally sound, because it is. Your argument is that 'If scaled up several orders of magnitude this device could cause dangerous explosions.' This ignores two very important realities:
1) There isn't a reality in which these devices get scaled up to that size.
2) The real danger with fission is radiation, not explosions, which fusion reactors will produce in smaller quantities than a banana farm.
Pure fusion power, even in its largest, most powerful, Elon Musk fever-dream incarnation, is safer than even the safest fission reactor, because there is no way for it to create a boom larger than it's vessel was designed to produce.
