There is nothing g to “disagree” about. Of course systemic changes are required. But if the individual improve their actions it will have a meaningful impact too

Without systemic change the impact of individuals wont be meaningful. Maybe on a spiritual level but they won’t contribute meaningfully to the climate change (or non-change)

It won’t and believing it will is part of ensuring nothing changes. All energy you spend on personally changing should be instead spent lobbying, organizing, and otherwise working politically to effect systemic change. There is no value in individual change. It’s worse than doing nothing.
