But someone has to pay for the construction and maintenance of those "freeways", so "tollways" were developed. In fact ...

Toll roads have existed for at least the last 2,700 years, as tolls had to be paid by travellers using the Susa–Babylon highway under the regime of Ashurbanipal, who reigned in the 7th century BC. Aristotle and Pliny refer to tolls in Arabia and other parts of Asia. In India, before the 4th century BC, the Arthasastra notes the use of tolls. Germanic tribes charged tolls to travellers across mountain passes. Tolls were used in the Holy Roman Empire in the 14th and 15th centuries.
Since revenue from gasoline taxes are declining (thanks to the proliferation of electric and hybrid-electric vehicles), the money to pay for the construction and maintainance of highways are being met by converting those highways to toll ways.
While you may not like tollroads, millions of people appreciate them for being well-maintained, relatively free from traffic jams, and for just being available.
