The assertion that the decline in investments would have triggered the announcement of quotas in Australia is a vulgar simplification and does not take into account the complex legislative process.
The implementation of regulatory quotas is a deliberate political decision, the result of structural considerations regarding cultural sovereignty and competition, not a simple reaction to an economic fluctuation.
For example, the introduction of the digital services tax in France was not a direct response to a sudden drop in revenue, but a well-thought-out fiscal strategy.
Substituting correlation for direct causality is a manifest error of judgment.
