Socializing those things would also make basic entrepreneurship much more practical and make failures of entrepreneurship much less harmful (such as the many restaurants that fail in their first year), hugely benefiting the economy as whole.
I'd like to see data from other parts of the world, but at least for France, this argument may hold some water.
A crude comparison of business formation between France (with socialized healthcare / retirement) and the US (without those), shows that the numbers are fairly close. Data is for 2020, which saw a 4% rise for France, whereas in the US numbers were stable. France also doesn't have as much of an "entrepreneurial" culture as the US, meaning people are much more likely to "look for a job" rather than found their own business.
Interesting statistic. The one year may be a bit of an outlier for the relationship. If you look at the 2010-2020 period in the data linked above, the US had a significantly higher growth rate in business formation (75% vs. 36%). This is not explained by growth in population which were identical over the period (7.2%, wikipedia).
