Err, I have to respectfully disagree with some of your points.
So firstly, while you may not have experienced any issues with root damage from pine trees in your area, other regions may have different soil conditions or water tables that make planting large trees, including pines, a risky choice. Root damage can occur over time and may not be immediately noticeable, leading to potential problems with foundations, driveways, and other structures...
Secondly, while planting pines along a back fence for traffic buffering sounds like a good idea in theory, it's worth considering the long-term impact. As you mentioned, it could take years for the trees to provide effective noise or visual buffering, and during that time, the trees may require maintenance which could just add to the overall effort and cost((
And thirdly and the last one, while big trees like pine trees can be beautiful and offer benefits, it's important to consider regional factors and long-term maintenance :)
Everyone's perspective and experiences may differ, and it's important to respect individual choices and limitations when it comes to property decisions.
