Probably and it may be infeasible to raise the cap further in the future even if that would be optimal.  However with a 20MB or 33.6 MB* (2^25) block size Bitcoin at least has the potential to exist as a backbone of sorts and it does provide us breathing room.  Once again I am not advocating any particular size limit, timeline, or method to raise the cap just that the idea of permanently keeping a 1MB block size just fails basic math and reasoning.   If the post convinces some people to go from "never raise the limit" to "I have concerns how can be raise the limit in a way which addresses them" then it served its purpose.


* The only "limit" definitively set by Satoshi.
