Quote from SmmenenAnd that's fine, but my response is: let's let the market work that out. Theory suggests that competition is better for consumers. While it might actually be the case that PTQ TOs price near or at where a competitive market does, there are good reasons, or at least some evidence/reasons, to think tha they don't. Moreover, all of the benefits of market competition would acrue under such a system, benefits that can't even be spelled out here.
And I'm saying that the risks of changing to such a system would be bad for Magic in the short term, potentially so much so that it could cause severe harm and setbacks. In the long run, it all evens out, but in the long run, we (and more importantly, possibly magic) are all dead.
