Why do you think that? Regress without covariates just estimates the
mean (the constant), and robust standard errors gives you robust
standard errors for that mean. Similarly, bootstrap would give you a
bootstranp confidence interval for that mean. Both are valid attemps
to work around non-Gaussianity.
