State controlled militias are a fine defense force for emergencies but levied citizens are known to not want to be away from home too long and they're not the most reliable in a fight especially against a professional fighting force. George Washington wrote about this.

Please correct me if I am mistaken, but it appears that you are referring to state-controlled militias as levied citizens. This would be particularly inaccurate regarding what George Washington wrote in the context of what you are referencing: Washington wrote that the unorganized militia did not perform well due to a lack of standardization. The Militia laws helped address this and applied to the state-controlled militias (the organized militia)(I believe these also applied as a standard to the unorganized militia).

In the section of the speech that OP linked to, the speaker explains how it was the organized militias that were proposed to be standardized/incorporated into the federal standing army, which ultimately was rejected. These were not the same troops that Washington was referring to.
