If the government decides to privatize utilities like electricity/gas or whatever, then sure it is freedom for some rich business owners to open up new businesses. However, this also results in those utilities becoming profit driven (as opposed to being for the public), and literally everyone in the country having to pay much more than they were paying previously.

My country had electricity privatized around 4 years ago, and in result we have to pay a lot more, not to mention about numerous fraud cases that were all over the news during and after the privatization period.

If you think that rich business owners being able to open up a couple of business at the expense of fucking over the public is a good thing and being against it is some weird hexbear delusion, then I'd advise you to get out of the libertarian bubble and look at the real world instead.
