Policy makers don’t need to be homebuilders - as long as they listen to them and learn what works for the industry. The new entity they’re promising seems to focus on ‘affordable housing’ which means publicly funded housing rather than being focused on resolving ‘housing affordability’ as a whole. But it will help supply regardless.

Congrats for thinking like this when you’re young!(I wish I had!) Yes, make a plan! That’s the first step. Write down your goals (what you want in life and need the money for and when) Then do your risk profile. Then check that you have the basics of personal finance in place (no debts, emergency fund, etc) There are courses and online resources for this. McGill has just updated their personal finance and investing online course!
