Not all natural is all the benefit.

It is not even go far with little effort. It is go far or close without having to mind weather unless it is really windy when trees fall on the roads.

When it is -15 degrees celcious or is pouring rain you don't care, have fun riding bicycle in such rain.

So not caring about weather/elements is not natural.

Most of the time I have to carry ~20kg of stuff with me, laptop, coat, umbrella, some food, some water. Getting groceries on my way back home.

Carrying ~20kg or even ~30kg of stuff around all the time is totally unnatural. Well going 50km away from your home on a daily basis is not natural at all. But a lot of people to make ends meet need to go even 100km away on daily basis.

Yes, going to your local shopping center with a car where you can walk in 10 mins and carry 5-10kg of goods is supper shitty and for 5-10 kg one could cycle with it. Going "all car culture" is bad is not the way to go, because for many people alternative is to "sit in one place and die" as they don't have shopping center available in walking distance.

As someone who has bicycled most of my life in Scandinavia, neither pouring rain or -15 degrees are much of a problem. You are dressed for the weather and you soon don’t even think about it. The only reason that I stopped bicycling in the winters for a while was because the car drivers tend to become “bicycle blind” when it’s snow on the ground. I’ve had drivers stare right at me and then almost hitting me because they obviously didn’t understand what they saw (a bicycle in the middle of the winter).

I don’t understand why you think you need to bring 20 kg of stuff every day. That is what I carry for a several day camping trip.

Right, what's more independant than a bike? Cars, machines with thousands of moving parts that must be maintained with gas, oil, tires, insurance, registration, and other maintenance aren't in my view.
