I'm not sure if you can discount the infrastructure behind bitcoin. Others might do the same or better, but to catch up to bitcoin in terms of distribution or acceptance, seems far fetched.
Distribution of Bitcoin is far from ideal and will only get worse as mining becomes more and more centralized. As for acceptance, I am not sure the widely publicized numbers are anywhere close to reality. It's very hard to live on Bitcoin unless you are in a very big city and make a lot of efforts to find vendors who accept Bitcoin in exchange for food, shelter, etc. Same goes for infrastructure: the programming part is easy to adjust for crypto 2.0 technologies, this crypto movement has just started, the first mover advantage of Bitcoin is not that big, except in people's minds. Well, marketing and usefulness help to change people's perception rather quickly.
