Dude no.
If you hone razors that have edges in ok condition, you only need a 3K/8K or 4K/8K or a coticule for example.
If you have the intention of honing razors with dinged up edge, you could add a 1K stone.
If you have the intention of honing lots of razors, add a DMT D8C lapping plate for keeping your stones flat.
there is absolutely positively no reason whatsoever to buy that amount of stones, just for the sake of sharpening a razor. More stones 'can' make life easiers, but it is silly to buy 500$ worth of stones for the sake of maintaining 1 or 2 100$ razors.
To make an analogy, for personal travel you have feet, a bicycle, and a car. that is all you need for most of your traveling needs that are not really long distance. Sure, you could add a segway, a skateboard, an SUV, a long haul truck, a moped, a quad, a trike, and several other things, but you don't NEED them at all. Not if all you'll really do is move about in your local village.
