I need money to do research, available grants require achieving specific measurable results during the grant (mostly publications fitting specific criteria e.g. "journal that's rated above 50% of average citation rating in your subfield" or "peer reviewed publication that's indexed in SCOPUS or WebOfScience", definitely not a preprint or blog), and getting one is also conditional on earlier publications like that.

In essence, the evaluators (non-scientific organizations who fund scientific organizations) need some metric to compare and distinguish decent research from weak, one that's (a) comparable across fields of science; (b) verifiable by people outside that field (so you can compare across subfields); (c) not trivially changeable by the funded institutions themselves; (d) describable in an objective manner so that you can write up the exact criteria/metrics in a legal act or contract. There are NO reasonable metrics that fit these criteria; international peer-reviewed-publications fitting certain criteria are bad but perhaps least bad from the (even worse) alternatives like direct evaluation by government committees.
