I agree in principle, but that won't stop someone from fighting with shift reduce conflicts or dangling elses for hours on end before giving up. constructing an unambiguous CFG isn't trivial without experience, and it's tough to get that without bashing your head a few times.

Right, but if you just hand-write a recursive descent parser, you won't have to deal with shift-reduce conflicts. Dangling elses are trivial to solve. The nice thing about hand-writing a parser is that it lets you learn one new thing (how to implement a parser for a grammar) while taking advantage of what you already know (how to write, run, test, and debug code in some existing language).
Throwing a parser generator at someone means they end up learning the weird vagaries of that generator instead of focusing on their own language. Meanwhile, the resulting generated code is nigh-unreadable, so all of those debugging skills and nice IDE they have go to waste.
