Why is a lack of female players in top e-sports considered a bad thing?

During the last 10 to 15 years or so, so-called e-sports have become extraordinarily massive multi-million dollar competitions, with professional video game player teams (ie. they make their living playing video games), multi-million-dollar prizes, and millions of spectators. Especially in some countries (like South Korea) e-sport events can be absolutely massive, topping almost any other sports event.

However, people quickly started noticing a peculiar feature of the top professional teams: The vast, vast majority of the top professional players were male, with only extremely few rare exceptions. And all-female teams are almost non-existent (with some attempts at it failing miserably).

Like with everything else dealing with such things, rather obviously this is considered a "problem" and a bad thing.

But I have to seriously ask: Why? Why is this considered a bad thing?

Consider what it requires for someone to become a top professional e-sports player: To pretty much have no life outside of video games (and, especially, that one particular game you are a top player of). These people don't become top professional players by just casually playing the game a few hours on the weekends. This is pretty much a full time job to them. They don't do almost anything else than play that one particular game all day long, every single day.

In other words, pretty much in essence they don't have a life outside of playing video games (and that one game in particular). No offense intended to those professional players.

The fact that there are so few female top players merely indicates that the vast majority of women have a life outside video games. They don't like to be inside their room all day long doing nothing but playing video games. They like to go outside, they like to socialize, they like to have an actual life outside video games.

Why is this considered a bad thing?

Why are people so eager in seeing more women becoming anti-social shut-ins who do nothing but sit in their rooms all day long in front of their computers doing nothing but play video games?
