A large part of the "foreign ownership" plaguing west-coast cities like Vancouver and Seattle is capital flight from China. In this case, real estate has the valuable property of being harder for a foreign government (who happens to be the government to which the homeowner is subject) to confiscate+liquidate than other assets, so said government will prioritize softer targets. Real estate as an investment class here is acting like a club on a car steering wheel—de-prioritizing theft, rather than inhibiting it.
