I don't know much about sports laws and particularly Spanish sports laws, but I think to do so would have to turn the club into a SAD (sports company) as opposition to an association as it is today, a different set of rules will apply, from tax rate to corporate governance etc. It is a red line for the club that we do not want to cross.
More importantly, if we were to go public, I think that means we have no ways of stopping some individuals or groups to purchase most of the shares and exert their wishes, influences and directions etc. on the club, essentially taking control of the club. If that happens then I suppose there is little difference between a club like that and those clubs privately owned by billionaires. Also there could be potentially infights between the different groups of the stockholders etc.
Identity politics is always part of this club, being a face of Catalonia and its culture, language etc. and to a lesser degree, Catalan independence movement. Not something that should be gotten rid of.
I think the club should always remain member-owned, but we should have gone to the professional model like Ferran Reverter wanted, basically staffing the club with professionals and running it like an enterprise and corporate with merit-based hirings, promotions and reward systems etc. in place, with a CEO and executive team answering to the president and the board, not the presidential / "family club" model Laporta is turning the club into.
