Because the CRM is the seam the whole revenue org is stitched along. Marketing scores leads into it, support reads accounts out of it, finance reconciles against it, and the board deck is generated from its reports. Ripping it out means rebuilding all of that at once with no downtime, while the sales team is mid-quarter. That risk is worth more per year than the license, which is exactly why the license costs what it does. A solo consultant tracking forty relationships is in a completely different situation and is mostly paying for guilt.
