There are too many initiatives on the ballot. Initiatives cause ballot clutter. Voters do not like long ballots. Initiatives benefit one philosophy. People vote selfishly.
Many initiatives are bad ideas.
Initiatives place extraneous material in the constitution. Initiatives create tyranny of the majority. Initiatives make the legislature unnecessary. For various reasons, Polhill finds none of these allegations against the initiative process persuasive. He notes that the number of initiatives rarely reaches one percent of the number of bills considered by a legislature.
