Understood as the option to exit an asset market at any moment, an option made possible by the certainty of finding a counterparty (a buyer) and by a volume of activity that assures the absorption of the exit transaction (the sale of titles) by the market without significant price variations, liquidity is a promise of perfect reversibility offered to financial investors. [...] Keynes had already noted the fundamentally anti-social character of liquidity,39 as the refusal of any durable commitment and Desire’s desire to keep all options permanently open – namely, to never have to take the other into consideration. Perfect flexibility – the unilateral affirmation of a desire that engages knowing that it can disengage, that invests with the guarantee of being able to disinvest, and that hires in the knowledge that it can fire (at whim) – is the fantasy of an individualism pushed to its ultimate consequences, the imaginative flight of a whole era.
