Not all monopolies are created equally. Some have greater cost to society. For example, Qualcomm has an essential patent which grants them a monopoly over certain communications technologies but it has been mitigated by requiring them to license it in a fair, reasonable, and non-discriminatory (FRAND) way.
A monopoly by Standard Oil was pervasive in all of daily living because by the early twentieth century, they had control of more than 90% of the country's petroleum fuel production and logistics which they abused to keep any competition from ever gaining a foothold. By 1911, they were dissolved by the Supreme Court as per Sherman Antitrust Act.
VBucks and Fortnite are not pervasive in all of daily living, it is a tiny market and the monopoly is one which can easily be managed by society without breaking up the company.
