We certainly don't "need" high-end basses with intricate active electronics. We don't need any bass. The world was fine for many millennia without the electric bass. A P-bass with no effects straight into my GK does more than I'm capable of as a hobby bassist that plays P&W on Sundays and does fill in work and a few open mics. But plenty of folks love their Foderas with pickups that cost more than my entire rig. More power to them. World would be a boring place if everyone did the same things as me.
