In general yes, if the protein works as a good drug the matter of synthesising it is a solvable engineering problem.
However we are not talking about a pill. We are talking about a daily injection. We are also not talking about completely reversing all aging but some aspects while likely suffering side effects.
Given the priors in a case like this, it’s unlikely that everyone will soon take daily injections of the protein.
