I guess not; people should design their web pages with em-based font sizes and have everything relative to the base font size specified by the browser. (Unless there's a good argument against this practice I'm not aware of.)
If you're regularly having trouble reading a page then it doesn't hurt to specify minimum font sizes. I personally never run into a page I can't read thanks to them.
