Haphazard sample
If the population is not evenly dispersed then the sample may unfortunately come from a section that is not typical of the population. That means the sample will not be representative of the population and so any estimates for the population, based on sample statistics are biased and therefore unreliable.
In systemic sampling, we select some starting point and then select every kth (such as the 50th) element in the population. Per Elementary Statistics by Triola, page 24

Sampling distribution in statistics works by providing the probability distribution of a statistic based on a random sample. An example of this is figuring out the probability of running out of water on a camping trip.
Sampling error occurs when the sampling protocol does not produce a representative sample. It may be that the sampling technique over represented a certain portion of the population, causing sample bias in the final study population.

conclusion to the statistics sampling
If the population is not evenly dispersed then the sample may unfortunately come from a section that is not typical of the population. That means the sample will not be representative of the population and so any estimates for the population, based on sample statistics are biased and therefore unreliable.
The answer depends on the cost of the various options and the required accuracy of the reusults.
The answer depends on which parameters are to be calculated.

The sample is of little use in making estimates for the population as a whole unless it is known exactly how it is non-representative.
