I do not rule out that with a lot of passion and plenty of effort you can also do decent beer.

Nevertheless I never heard about anybody who would succeed to make at home better beer than that we drink normally in Czechia (also never really made any investigation though) - but may be it can be better than the local Chinese beers :).

But the main point for all people who did own beer was not that much superior taste but the self satisfaction which drinking their own beer brought to them - sometimes such feeling is more important than the beer quality as drinking should be about enjoyment with friends :)
