Per ARIN (and pretty much all regional RIR) rules you're not allowed to purchase IPV4 space without proving the need for it, with a moderately thorough review process (https://www.arin.net/participate/policy/nrpm//#8-5-specified-transfer-recipient-requirements https://www.arin.net/participate/policy/nrpm//#8-5-specified...) Any other purchase reason is likely to result in ARIN pulling your "ownership" entirely when they discover it. From what I understand most of what's being sold off right now on ipv4 auctions are from companies who had too much IPV4 that they no longer need, or companies that were liquidated.
