The main benefit with SSDs is that they are taking more steps to make the flash ram last longer (increasing the read-write cycles), and more load balancing to improve overall disk life. (flash ram 'wears out' over time)
Simple CF cards are not likely to include this level of sophistication. That means that you will wear the card out with standard log file and /tmp wibbling, and, if you end up with swap on them, they will die really quickly.

Many people do use cf and even sd for hard drives successfully, but they are careful to mount the drive read-only, and create RAM drives for areas that really need to be writable. With the improvements with mount -union, it is now feasible to mount a writable filesystem over a readonly folder. Previously, they had to copy a default directory tree into the ramdrive during startup.
The only dumb question is a question not asked.
