Botnets buying up IPv4 address space

The important outcome is that transfers are documented. Making it easier for sellers to update Whois (so it points to the buyer) will encourage documentation.  If "needs justification" is ever a disincentive to update Whois, then it will discourage documentation.

Granted, a seller that doesn't update Whois should be more worried about the reputation of the buyer. But regardless, it is incorrect to assume that "needs justification" will prevent bad actors from acquiring address blocks. Even bad actors can justify their need, and some of them might even (*gasp*) lie about it in order to get what they want. The result would look like a normal transfer (with justified need, a Whois update, etc) and yet would result in a bad actor becoming an address holder.
