if you are on the 2020 or 2023 code cycle, you will need an outside emergency disconnect at the house.

Code requires an emergency disconnect outside of the house. I'm guessing it is an AHJ interpretation if a disconnect breaker at the meter 150' away from the house counts. It is clearly a disconnect, and it is clearly outside the house.

Copper because it is top shelf! Why do I only use metallic wiring methods in my own home?

They fixed that in the 2023 code with 225.41. With the disconnect 150' away from the house, the house is a second building fed from a remote service. The rule in 225.41 says outside at a readily accessible location within sight from the house, so no more than 50' away from it.
It would also be covered by 215.18 for feeder supplied distribution.

This is my understanding (according to the EC)

Hard to deny the beauty of stranded copper.

We're on 2017 NEC

From all the info I can gather, Mass is on the 2020 code.

Not likely, they are always the first state to adopt the new code. Typically in the first few months of the code edition year.
On February 17, 2023, the Massachusetts Department of Fire Services and Board of Fire Prevention Regulations (BFPR) published and promulgated a new edition of 527 CMR 12.00, the Massachusetts Electric Code. 527 CMR 12.00 is an amended version of the 2023 Edition of the National Electric Code (NEC), produced and published by the NFPA as NFPA 70. The new version of 527 CMR 12.00 is effective March 1, 2023 and applies to all electrical permits applied for following this date.

You're correct, I was looking at Maine on the map on MH site.
Regardless, it's not on the 2017 unless some sort of local amendment.

The building permit was pulled a while back, and the service installed even earlier. Not all towns adopt the new codes overnight.

I though MA is a state wide adoption state, not giving the towns any choice? However it is based on the date the permit is pulled.
