AIBU about rewilding?

[monpetitlapin]

I'm in two minds about this and would be interested to know what wise Mumsnetters think. On one hand, I think Titchmarsh is right that "rewilding" probably produces less biodiversity than cultivated beds that are thoughtfully planted, but on the other hand, surely "rewilding" is better for manicured lawns?
So AIBU to think he hasn't entirely thought this through?

I'd love to leave our front garden grassed area to go to seed regularly - we don't use it as a garden per se, but the neighbours literally knock on the door and complain. Their concrete is much nicer looking apparently
