I imagine the reason why all the costs are so high is to help prevent the spread of Covid from other countries. While cases in Switzerland are much lower than the UK, there are still active cases. The government is trying to get people to understand that unless there is a real reason for travel, to not do it. A lot of people have been travelling even around the UK for silly reasons, willingly knowing they're going to get fined and are content with receiving one.

Ultimately I think it comes down to how necessary are your travel requirements right now, and whether or not you feel willing to accept that travelling from country to country right now, comes with quite literally, a cost.

If you have to travel for an exceptionally good reason, you could seek out advice either from perhaps the Citizens Advice Bureau in the UK, or something similar in Switzerland and see what they can suggest.
