There is many people who has different vision on the cryptocurrency. And if one have an instrument for creating his own coin, he will obviously create it. Why he should deny himself the pleasure of creating a new cryptocurrency?
People will always have vision and an idea and one thing with idea in the past is that when you do not have funding or when you do not have a product and you find it hard to even project it out there or have the funds to push it, the project eventually becomes dead. This is one thing I have known the blockchain technology to have changed and people with ideas are really taking advantage of it which is why we keep seeing more coins being created, on and on.The only thing here though is that, there are also some greedy ones who are just out there to scam and really do not have any product to want to give than to cart away with investors fund, which is why it is important to always invest in a project with a product and not an empty promise.
