If you want to accelerate quickly, it would be a lot easier to use a big chemical rocket than a fusion reactor, and would require getting less mass into orbit given our current understanding of how to engineer fusion reactors.
Would you invest in a fusion powered ocean going cruise liner, construction beginning next year? If not, then don't even think about investing in fusion reactors in spaaaaaaaaace.
