Irrational fear of controversy, and of the idea of hard forking in the future (i.e. making decisions) is not an adequate reason to push a reckless regime of exponential scaling.
Have you considered that it's technically much better to have generous limits which you can reduce via soft forks if needed, than having the limit set too low and then be forced to do another hard fork to raise it.
Also we've already had 32 MB limit in Bitcoin's history and it created no problems. And the fact that Satoshi's idea was to remove blocksize limit entirely when light clients became available.
The eventual solution will be to not care how big it gets.
