Paris had 2.9 million people in 1921 and 2.2 million today. Is it really overpopulated?

Your numbers are from the city of Paris. Most people riding in the metro during working rush hours are not from the city of Paris, but from the suburb. The suburb population in 1921 was 4.8 M in 1921 and 12.2 M in 2010. https://en.wikipedia.org/wiki/Demographics_of_Paris#Historical_population https://en.wikipedia.org/wiki/Demographics_of_Paris#Historic...

  The RER was created in the 60s for this purpose and continually expanded since, no?

    The RER brings riders from the suburbs into the city, but doesn't add to the infrastructure for transporting them once they're in Paris.

      There are RER stations within Paris: everything within zone 1 is in the city of Paris: https://parismap360.com/carte/image/en/paris-rer-map.jpg https://parismap360.com/carte/image/en/paris-rer-map.jpg But even if cutting prices is within Paris only it will probably affect suburb-Paris traffic, because it changes the cost of a trip to Paris, possibly now cheaper than driving. The article is light on details, but it looks like these measures are taken by the city of Paris with the aim to reduce the traffic within the city.

    The RER contains the western world’s busiest train line with over a million passengers a day. It’s become a victim of its own success. In fact moving block signalling was invented to boost capacity on the RER. The government is currently investing $25B in building more relief capacity, but who knows how much investment you’d need to handle the unlimited travel demand caused by a free fare.

Just like Tokyo's density is actually lower than Paris, the elephant in the room is the number of people who commute to the city center every single day. That is the only metric that matters for transports.
