With technology or a product that people will voluntarily pay for, you can make a specific, measurable, concrete difference in a bounded timeframe. If you fail, you can be sure to do so without causing immense suffering across a whole society in the way that government actions sometimes do when they go wrong. If you could "fix the underlying issue" in a permanent way without unintended consequences, that would be better, but no one knows how to do that reliably using politics, and the failure modes of airbnb, uber, and tesla are gentler than the failure modes of politics.
