De-bogon not possible via arin policy.

Fyi, I just was rejected from arin for an ipv4 allocation. I demonstrated I own ~100k ipv4 addresses today. My customers use over 10 million bogon / squat space ip addresses today, and I have good attested data on that. But all I can qualify for is a /18, and then in 3 months maybe a /17. This is called slow start ? For an established business? Just fyi, de-bogoning , or private rfc 1918 is not really an option even with strong and consistent demonstrate load. Any suggestions on how to navigate this policy ?
