Basically, the “no immigration” path i

That is a strawman of your own creation. All I said is that I want my children to have the opportunity to have kids of their own if they wish to, which currently seems unlikely because our government does not prioritize fostering the conditions under which young people choose to start families.

I would prefer Canada to grow primarily through its own means rather than relying so heavily on immigration to avoid economic collapse.

If you prefer not having kids or grandchildren, that's fine by me, but don't assume we all want the same things.
