There should be a point when you create something. It's easy to create a new token from scratch and it has been easier since the day Bitcoin was created to create a new token because you have an open-source code of Bitcoin, just copy/paste it and edit, that's all, that's what LTC and some other coins are.
It's easy to create a Bitcoin fork but seriously, what's the point? You can't get the majority of miners to follow your fork, so create a fork and be alone, what's point of this? That's why people aren't creating a fork, it's completely pointless unless you have billions of dollars, connections and power. Probably Elon Musk can create a fork and get a solid fanbase but there are also many other things on the table, including the reputation among developers.
Yes it is easy to copy and change Bitcoin open source code to make new coin but it is very difficult to create successful fork. And Litecoin was made by changing Bitcoin code but it is not true fork like Bitcoin Cash which split from main network. Main reason most forks fail is that they can not get support of miners and developers and users. As you correctly pointed out successful fork requires huge amount of power and money and influence. This shows that true value of cryptocurrency comes from community that supports it not just from code itself.
