It is utter fallacy that MPLS is costly, MPLS is systematically and
fundamentally cheaper than IPv4 (and of course IPv6 costs more than
IPv4).

However if this doesn't reflect your day-to-day reality, then you can
always do MPLSoGRE, so that core does not need more than IP. So in no
scenario is this narrative justification for hiding MPLS headers
inside IP headers, which is expensive and complex, systematically and
fundamentally.
