I'd say at that point it's essentially compensation for personal suffering.

Yes, BYOIP as a feature does not seem complex enough to warrant paying for an Entperise license. But the kind of customers who need BYOIP (especially if they need it to avoid harming your IP reputation) are likely to be at a higher risk of being flaky or otherwise painful so this is very much a tax on running that kind of business (just as porn sites often find it hard to find payment processors because of the high risk of credit card fraud).

As a freelancer I have absolutely made offers at 10x my going rate for client I did not want. The idea is that if they really want me to work for them, at least I get reimbursed for the suffering that will entail. This kind of pricing structure is no different.
