It depends what you mean by "from space". The ISS is in space and also _in orbit_, so is moving laterally at about 17,500 mph / 28,000 km/h / 7777 m/s / Mach 22 (1)
It's not just about falling, it's about the heat and stress of hitting the air when moving sideways at nearly 8 kilometres per second.
The "sub-orbital hop" scenario that Bezos and Branson do involves technically "falling from space" but is very different as they're not moving sideways.
