It's not like that if we developed something in terms of bitcoin then we will have it done right. It's all about the blockchain. The whole crypto works on it and so as to why we need to develope the blockchain first. :-)

Now the question is whether we are in the right direction in that one or not. I believe we are, it's just that we are not moving fast enough to see those changes. So many development through the forks and segwit implementation last year. It has speeded up the process but it wasn't sufficient enough. Now is the time they need to start over and they will take time to achieve that so we need to have patience and lot of it. :-)
