I'd argue two dime-a-dozen pump and dumps is dwarfed by the magnitude of issues that letting politicians exploit trading using policy-making. The profits they earn is hardly the issue. The issue is they are motivated to set policy or spend as much govt money in a way that benefits their portfolio. A politician spending an extra billion of public funding to make (say) a half a million themselves is a real issue.
