Using List.Sort in In Unity, why do I get a "does not implement right interface" error when trying to sort my list of objects?

Removing content that was not impertinent to the question, and as such, was counter productive towards a minimal viable example

I am trying to create a crafting panel that sorts the list of items you can make alphabetically, yet I cannot figure out why .Sort() is not working. 

What I have is a game object that holds a list of all the items you can make and the requirements, then in my crafting script I access the game object for the list and display the info. 

Everything works fine until I try to sort anything. craftDatabase is what I need to be sorted. Also, it needs to be sorted by ItemID.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class CraftDatabase : MonoBehaviour 
{
    public List<Blueprint> craftDatabase = new List<Blueprint>();
}

[System.Serializable]
public class Blueprint
{
    public string itemId;
    public int itemAmount;
    public float itemCraftTime = 1f;
    public CraftPanel.subsections subsection;
    public CraftPanel.workstations workStation;
    public List<requiredItem> requiredItems = new List<requiredItem>();

    [HideInInspector]        
    public string desc;

    [System.Serializable]
    public struct requiredItem
    {
        public string itemId;
        public int itemAmount;
    }
    
    public Blueprint()
    {
    }
}

Unity3D C# Sort

I am trying to create a crafting panel that sorts the list of items you can make alphabetically, yet I cannot figure out why .Sort() is not working. What I have is a gameobject that holds a list of all the items you can make and there requirements, then in my crafting script i access the gameobject for the list and display the info. Now as it sits everything works fine until i try to sort anything. craftDatabase is what i need to be sorted. Also it needs to be sorted by ItemID.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class CraftDatabase : MonoBehaviour {

public List<Blueprint> craftDatabase = new List<Blueprint>();
}

[System.Serializable]
public class Blueprint
{
public string itemId;
public int itemAmount;
public float itemCraftTime = 1f;
public CraftPanel.subsections subsection;
public CraftPanel.workstations workStation;
public List<requiredItem> requiredItems = new List<requiredItem>();

[HideInInspector]
public string desc;

[System.Serializable]
public struct requiredItem
{
    public string itemId;
    public int itemAmount;
}
    
public Blueprint()
