> We can launch things to space, yes. But we don't have any vehicles that have life support, abort, or re-entry capabilities.

Dragon has all three. The reason there are not people it right now is just that there is not enough experience with it to rule it safe. If the risk was ruled worth it, the very next CRS mission could take people up to the ISS.

While it does have "a life support system", this basically means ventilation and some environmental monitoring & control (incl. N2 and maybe O2 for repressurization). It does not mean that it can sustain a vertebrate let alone humans for a substantial period of time. Experiments sent to the ISS containg lifestock always have their own life support system embedded.

The integrated life support system is designed so astronauts can access Dragon while attached to the station, not to sustain them. It receives all utilities from the station and returns "used utilities" (i.e. consumed air) back to the station's systems. It cannot reprocess/regenerate the components by itself.

dragon V1 has no abort capability
