As an amateur programmer, there is a real problem with more bank space. It takes memory to make it work. Whether RAM, Disk space or however Jagex makes it work, to add more bank space would require more hardware/software than may be possible. Think about it, one server can hold 2000 players. Each one has their own bank account and farming patches. I know my machine at home can only fit so much RAM, only so many Hard disks, only so many peripheral cards. That may be why there is a drag on creating more space in the bank. And on a side note, f2p is the demo version of RS. You should not get all the bells and whistles that members get. Jagex is a business which sells RS as a product. If they made the demo comparable to members, no one would buy membership and Jagex would fold leaving us players with no RS at all.
