TLIK, there are definitely those who use Purim as an excuse to do what they would like to do year round.
There are also those who have no desire to get drunk during the year but do so on Purim, for the mitzvah. The gedarim for the mitzvah are subject to machlokes, like much of halacha. Getting extremely drunk is one legitimate shittah, in fact, that of the Mechaber.
Anyone who deligitimizes that shittah “is creating halacha to fit his own desires”. How shameful.
