Beyond the Standard Model (BSM) physics has often been criticised as "speculative", but it is generally accepted that the Standard Model cannot be a theory-of-everything as it does not incorporate gravity, etc. Other reasons why BSM physics is required include:
The Standard Model requires renormalisation.
The Standard Model has a large number of free parameters.
The Standard Model does not include gravity.
