So basically any sail capable of actually using the target star's magnetic field to decelerate would be too massive to build on the ground and require enormous amounts of energy to actually accelerate, and any probe small enough to actually accelerate via laser would be to tiny to generate enough power to communicate any data at stellar distances?
