I feel very strongly that states should be able to run limited-time, limited-cost experiment, even big expensive ones like this. That requires that people accept that the experiment ends, and do not expect it to be a new norm. If people expect an experiment to last forever, then it'll be too difficult to agree on what the next experiment may be.

Besides, I feel that it's stupid to think that the terms/rules which were chosen quickly for an experiment happen to be the best ones for the long-term future. If anyone says so, I think that implies that they haven't really studied what happened in the experiment.
