There's a recent post titled Four Fallacious Reasons to Estimate. It lists the usual suspects for why those spending the money think they don't have to estimate how much they plan to spend when they'll be done producing the value they've been assigned to produce for that expenditure. Let's look at each one in more detail.

The shortest time estimated to complete a specific project task or activity is known as optimistic duration. Performance Measurement Baseline. It is an estimation technique based on an expert consensus.

Agile software development is framed by a manifesto , a set of 12 principles, several methods. These are all focused on developing software, delivering that software to those paying the developers. The customer is accountable for knowing what Done Looks Like (in Unity of measure meaningful to their domain).

The paper on the Cone of Uncertainty is used by many in the No Estimates community as an example of why estimates are of little use. In this paper, there is data that does not follow the Cone of Uncertainty, in that the uncertainty of the estimates does not reduce as the project proceeds. Then there is some analysis.

Of course, No Root Cause analysis has been performed by these advocates, but it makes good click bait for their followers. Were there: Measures of Effectiveness. Measures of Performance.

I've seen estimates abused by bad managers, so let's NOT estimate and that will fix the behavior of Bad Managers." While the human behaviors are real and observable, conjecturing that decisions can be made in the presence of uncertainty without estimating the outcome of those decisions, there is no principle to support that conjecture.

For scenarios where the project under consideration does not yet exist, performance prediction using analytical modeling or simulation is necessary. Let's start with a definition.
