It is also understood that the source of funding for institutions which offer free services is taxes, fees, and levies from the general population. Regardless of what MMT proponents imagine, costs will eventually be repaid by resources, labor, or war.
I find it intellectually dishonest to advocate for “free” services without acknowledging how those services are funded. It does seem more of the population is interested in immediate gratification regardless of long term costs (see deficit spending, consumer debt, etc.), but that doesn’t make the cost disappear because it is ignored. It’s no different than suggesting because birds fly, they must not be affected by gravity.
I disagree with your opinion in the third paragraph, but I think we can agree to disagree.
