In the UK, you are normally not allowed to have the prefix 'doctor' with an honorary doctorate. This is more of a practice in the United States.
People who are awarded honorary doctorates by good universities are people who have achieved a lot more than any person with a doctorate could only dream of, and do not normally boost their status - is HM The Queen receiving a Doctor of Civil Law degree of University of Oxford going to boost her status? Is Dr The Hon Louis Cha OBE, the biggest-selling living Chinese author (more than 100 million official copies sold on the strength of just 14 novels in traditional Chinese) and co-founder and first editor-in-chief of an iconic paper, receiving an honorary Doctor of Philosophy degree from University of Cambridge going to mislead the public on anything (he later read for an MPhil and PhD from Cambridge, and an additional PhD from Peking University anyway)?
There are cases where it is going to mislead the public. For example, a celebrity tutor in Hong Kong calls herself Dr Tann on the strength of an honorary doctorate (she hasn't read for a master's, yet) from Armstrong University. But ever if she did enrol and complete an actual doctorate from said university (which is not recognised by the United Nations or the US government, and has already been closed down), is that not misleading in itself? To go even further, there are people who are being accused of 'purchasing' non-honorary doctorates from unaccredited universities. How would that be any better?
This is, thus, a non-issue. Honorary doctorates from well-regarded universities are only given to people who have achieved way more than what a doctorate suggests you to have, and those who obtained the doctorates just by purchasing it are from dodgy places which should not have been recognised (and often are not) as universities in the first place. Even the less prestigious universities don't just award random degrees to random people: Kingston University awarded an honorary doctorate to alumnus Eason Chan, who is the King of Asian Pop, nicknamed 'God of Song', and released a classic album which Time has claimed to be one of the five best Asian albums. University of Victoria in Canada awarded an honorary doctorate to Sultan Vicwood Chong MBE JP who is an honorary dean, a multi-millionaire literally owning a city in China, a member of the National Committee of China on the strength of his donations to the university.
Even taking into account of the aforementioned celebrity tutor, you cannot be serious to think that any regular doctoral student has put in as much 'hard work' or achieve anywhere close to whatever any of these people have achieved.
Just like what then-Vice Chancellor of Cambridge said to Dr Cha when he enquired her on applying for an actual doctorate upon receiving his honorary one, there is no need to do an academic one any more because the ones who have been honoured have already moved way beyond that level of attainment.
Last of all, you cannot ban honorary degrees. They are business organisations, and in a liberal society, you cannot just ban a product that does not break any law. Whilst you can then enact a law to restrict this product from being sold, you can see from unaccredited universities awarding degrees that it won't work, and those organisations award them anyway.
