It reads like you are stating a fact, but really, it is a matter of opinion. Perhaps, you can just say what you like without invalidating what others prefer.
I think their opinion of that the city sucks is wrong, full stop, and that a change in attitude would see all the great things a city provides that nature does not so that then you can appreciate both.
To me, enjoying the good parts of both the city and nature is a better POV than shitting one one of them.
Let's put it another way. If someone says the France sucks, Germany rules. And someone replies "The France doesn't suck, here's a few reasons why". Why do you feel the need to jump in and defend the POV that "France sucks"?
I also listed spending time with people as a plus to the city. It's interesting that you left that out. I'd guess if the author had a job they loved with people they loved their attitude about everything else would change. The fact they're in a job they hate arguably taints everything else about their life. Commuting of course sucks if it's to a place you don't want to go in the first place. To me, commuting by public transport rocks because I got, on average, 50+ minutes of walking (25 each way) for free (added to the 20 minutes of standing on the train)
Because you're forcing your opinions on them. You literally said their opinion is wrong.
Saying France doesn't suck because they have good croissants is pointless for a person that doesn't like croissants.
You can't force yourself to like something just because "it would be a better POV".
Facts on the other hand can be right or wrong as they can be independently verified.
There is no way to prove "great" things cities can provide. Different people value different things.
I actually don't dislike cities and I didn't generalise that they are terrible.
London is one of the busiest and largest mega cities on the planet. It's incomparable to a city of ~400k people where you can walk in 45 minutes from the city centre to the boundary where the urban environment becomes a more natural environment.
The mega city is not for me, and I regret sacrificing quality of life for income. This decision is about rebalancing those two.
