I absolutely think, 100%, that children and young people who are experiencing mental health concerns should have access to high-quality treatment that's culturally competent and equitably funded, with low financial barriers.
The other parts of the question are packed with too many things to be able to give a resounding yes, but we need access to care for people across the lifespan. Intervention at an early age, such as making sure that kids, in particular, have access to those services and supports early on from a prevention perspective, is also incredibly important.
