Do you really think that the most valuable sports club in the world according to Forbes magazine (as of 2022)
https://en.wikipedia.org/wiki/Forbes_list_of_the_most_valuable_football_clubs , the club with the highest revenue of any sports club prior to COVID-19, the football club with the biggest stadium in the world, one of the most followed clubs in the world if not the most followed club in the world (if all social media is combined), one of the most successful football clubs in history and one of the most storied clubs is going to "disappear"? Talk about blatant ignorance. Barça have survived far harder challenges throughout its 123 years of history.
If shit hits the fan down the line, the WORST CASE scenario, is us becoming a toy of some billionaire or state like 99% of all other European top clubs nowadays. Either a complete sale or a partial sale by selling parts of the club with the approval of the socios as that would be needed.
Barça and RM are pretty much unique in being 100% owned by its fans (socios) to this very day. The only other top club/historical club in Europe that has a similar ownership model is Bayern but they are not 100% owned by their fans any longer.
