Yes, a simple random sample is considered valid as it ensures that every member of the population has an equal chance of being selected. This randomness helps eliminate bias and allows for generalizations to be made about the larger population based on the sample. However, the validity of the results also depends on the sample size and the proper execution of the sampling method. Properly conducted, it provides a reliable foundation for statistical inference.
A reason for requiring a sample.
Take a simple random sample.
The answer depends on how the sample is selected. If it is a simple random sample, of size n, then it is distributed approximately normally with the same mean as the population mean.The answer depends on how the sample is selected.

simple random sampling
That is known as a simple random sample, or SRS.
at random to represent the population
simple random sample is to select the sample in random method but systematic random sample is to select the sample in particular sequence (ie 1st 11th 21st 31st etc.)• Simple random sample requires that each individual is separately selected but systematic random sample does not selected separately.• In simple random sampling, for each k, each sample of size k has equal probability of being selected as a sample but it is not so in systematic random sampling.

A sample needs to be random and if not a simple random sample of the whole population then a stratified random sample (there are different ways to stratify). Otherwise the study is a waste of time.
A simple random sample is good!
