Is there any reason NOT to eliminate all street parking?

New to the CS2 here, I have a city of about 180k. Despite effective road hierarchy and traffic management, it was just getting too dense for all the personal cars.

I removed every bit of street parking on the map and maxed the taxi price. This completely solved my traffic problem. I understand IRL this would help in dense cities, but this solution felt so easy and effective as to be unrealistic.

Are there others who have done this? Shouldn't the citizens complain that they can't easily get where they want to go?
