I think we need some perspective. If the variant (or any other variant) is more transmissible ( and comparing transmission in the UK to transmission in India is like comparing apples and pears even if you disregard ongoing restrictions) then that, in itself, is something to keep an eye on, but not really anything to worry about. Lots of things are easily transmissible, including the common cold and flu. The factor of concern needs to be focussed on whether something is either causing significant levels of serious illness or death. And again, yes, it is happening in India but there is absolutely no evidence that that translates into the same impact in the UK.
As others have stated here, nowhere is aiming for zero Covid. Because there is absolutely no way on earth that, barring a miracle or the virus suddenly burning out (which does happen, but is really rare) that Covid will ever go away. So we have vaccines now that will help (eventually) the entire population to to reduce the most sever cases and many deaths. An artificial form of herd immunity. And in the longer term, transmission is probably going to become a good thing - the more people who get it and successfully fight it off, the more the population builds natural herd immunity. So eventually, in the future, it likely becomes what flu is - something that has some variation every year, and those more susceptible to the worst cases due to age or vulnerability have an annual booster every year - and the rest of the population, if they get it at all, phone in sick for a few days because they are feeling under the weather.
It seems hard to envisage that ever being the case right now after the year everyone has just had, but we need to remember that viruses emerge constantly, and some of those impact on the human race. It has ever been thus. You could argue that the advantage we had previously was that we couldn't have identified it if we tried, we couldn't have done anything about it, and we probably wouldn't have known anything about it either. In an age of mass communications, sometimes we all know far too much, and simultaneously far too little.
