The artist won't starve if all the basics of living are free. Universal basic income or some other scheme could maintain the means of economic transactions, but post-scarcity fundamentally means that everyone is taken care of to a minimum basic standard of living. Food, water, healthcare, shelter, sanitation, and safety are available by default to every citizen. An artist would only ever starve or suffer if they renounced the basics. The nature of economics and markets changes radically in ways we can't predict. Post-scarcity systems could be fundamentally unstable concurrent with fungible currencies of the type we use now. New mechanisms of valuation based on time and so on might take hold, or it might require distribution of resources in ways not yet considered. The point being that incentives and accumulation of wealth will be radically different to the extent that there's not a clean or obvious connection to current incentives that drive human behavior.
