So - if a 95% confidence interval is based on a sample which can reasonably be considered to 'randomly selected' (and a whole lot of usually unstated assumptions are satisfied) then it is reasonable to act as if the population parameter of interest is within the interval.
Regardless of academic arguments, this is the way confidence intervals are used (by 95% plus of users.....)
