I know of no disproof off hand. But I believe the normal process is to produce proof when making a statement rather than making a statement and assume it true until disproven. One problem with assuming a claim true until dis-proven is that a perfectly reasonable but opposite conjectures can also be produced. For example: "units which are on the market at a profitable rate are not removed from the market solely because the rate of increase in profit is constrained; profitable business tend remain in business if the profit remains at lest the same" Another example conjecture, for which there is evidence: "the market will only produce housing at the highest price range for a given area unless subsidized or required by law to do otherwise." So affordable housing will not be freely built whether rent controlled or not. IMO, it'd be best to have some positive proof before firmly committing to any claim.
