Online stores manipulate people very effectively into spending and regretting. Some people, with psychological problems, find it very hard to resist this.

Setting up a national state marketplace site which does not get funded by a share of what people pay would make it easy to fix this problem, as well as many others. It could allow people to specify spending limits for themselves, which the site would then enforce, even limits on various categories of products.

It could have clear rules set by law and official regulation. It could completely refuse to allow use of personal data for profiling. Even better, the site could offer anonymous payment through Taler and anonymous product pickup at post offices and elsewhere.

This system would eliminate the tax-dodging of Amazon and the lobbying power of Amazon.
