I don't know that cartridges are a whole lot more expendable than anything else. Sure if you play a lot of records its possible I guess to wear one out. But then you sell it used just as you would any other component. I always have. Then buy a better one, same as anything else.
Then when you get to the level you're talking about it really makes sense to get the Soundsmith Strain Gauge. Costs a little more than $7k but actually costs a whole lot less because with it you eliminate the need for a phono stage that could easily run you $5k to $15k or more at that level. Plus you get a cartridge with user replaceable stylus that is dirt cheap, relatively speaking.
It even has an upgrade path, the power supply being capable of elevating performance well into the stratosphere of the very best cost no object carts.
