Obviously we should all keep washing hands anyway as a precaution, but it seems that at the moment there is no proof that people are likely to catch C19 from surfaces.
The fear started with much-quoted research early on that said it could live on surfaces for up to two weeks, but this article (and others I have seen since) have explained that researchers used the equivalent of 100 infected people coughing on the same spot. Which is not going to happen. It actually has a much shorter life on surfaces, plus you need quite a lot of droplets to get infected: www.theatlantic.com/ideas/archive/2020/07/scourge-hygiene-theater/614599/
This virologist explains that we have as yet no hard evidence of transmission from a surface - it's possible, but seems unlikely:
And many of us have been touching shopping (c'mon, not many of us have disinfected everything coming into the house) and kids went to plenty of playgrounds over summer and didn't seem to cause huge outbreaks.
Of course, we can't all just 'decide' this for ourselves, but I do wonder what it would take for the authorities to say 'You know what, keep washing your hands, but touching stuff is actually OK'? It would make a lot of stuff in schools, childcare, work, catering etc much easier and less stressful if we could lose the hyper-vigilance about touching things - as I can't see evidence that we need to maintain it.
