Astronauts on the ISS are currently zipping along at at 7.67 km/s just fine. The issue is acceleration, not speed. Tethers rotate fairly slowly, so the acceleration should be less than that of a rocket launch.
And we've all been zipping around the sun at 29.78 km/s since each of our inceptions.
Our Sun moves around the centre of the Milky Way at a speed of 240 km/s or 864,000 km/h, so do we plus or minus ~30km/s!
