Those users who can afford a high-end gaming machine don't find eGPUs a good thing for their laptops. But if you own a mid-range machine and don't have enough money to upgrade it to the latest-generation hardware, you can use a GPU, and they will allow you to get the same graphics performance as found in the latest gaming machines. The performance loss of external graphics card boxes is very minimal while, on the other side, it allows you to game on thin, lightweight machines.
