No. What qualifies you as a researcher is being able to output work that is accepted by your peers. Hence the peer review process is critical. You fail to meet this bar if you publish something in blogspot or even arxiv for that matter.
You are trying too hard to come up with excuses. The paper review process is double-blind, and nothing prevents you from publishing the same work in multiple journals. If your goal is to do meaningful contributions to science then "power dynamics" are irrelevant.
You do need to develop a meaningful network in the field if your goal is to collaborate with other researchers, but that's basically what everyone needs to do in any professional field.
Like I get that the current social norms around "research" might not be there yet, but if they refuse to adapt, I just see that as a reason to defund "research" and start from scratch.
