I understand the argument and that it would funded by donations - but I think even those donators would do better to give their heads a shake and send their £s to foodbanks - or educational trusts - or the Terrence Higgins - or whatever - instead of funding this particular monument. If you want to pay tribute to Bowie, fine, but maybe a very very expensive sculpture is not the way ... there are plenty of associated 'causes' (trans/gay acceptance and education, or arts funding, or coke rehab, or a thousand other things) which could do with some cash.
