No if you claim to be a separate nation, then you do need treaties. You can not have it both ways and the treaties do not provide for any of the above. And as for what you list, most people work, pay taxes, and pay for it them selves, not asking the ROC or the settlers or colonialists as they call us to fund it.  

Maybe these reserves out in the middle of no where serve no purpose and like ghost towns should be abandoned. Or live on your land with no services. And before you start screaming, my family Cree background left the reserve over 75 years ago and have never looked back.
