The file system (and associated baggage) exist because of a fundamental disparity between the speed (and nearness to compute) of smaller memories and the convenience (but relative slowness) of larger ones. While SSDs do certainly close this gap, I find it difficult to imagine that this gap will ever entirely close; if anything, physics guarantees that compute units with small, nearby memories will always be far, far faster than more distant memories. You might argue that SSDs are "fast enough" to dispense with the inconvenience that imposes, but I can certainly find things I'd rather do with the performance.
