like websites without javascript?

Working without javascript requires development time. Running old versions of HTTP doesn't. Version 1.1 is going to be fully supported for a long time.

Working without javascript requires money. Running old versions of HTTP requires ????.

Running old versions of HTTP requires nothing because people will need to support legacy devices for a long time, and it's obviously already implemented in all major components (Servers, CDNs, Clients, etc.)

???? != nothing.

Why run HTTP/3 if HTTP/1 costs nothing?

Where I work legacy gets dropped sooner rather than later.

I hope this bombs, er tanks.

You (will) run HTTP/3, because it is more efficient, meaning that your servers will be able to service more request.

You run HTTP/2 and HTTP/1, because a lot of people are still using that, and you don't want to lose them. This especially applies to mobile devices, many of which are stuck with software that cannot be updated for various reasons.

There's no threat of the majority of websites going HTTP/3 anytime soon. By the time that might be a possibility, Tor will catch up.

If it becomes the dominant way of serving web pages, you should realize that tor will add support.

The first one requires money be spent on every site.

The second one requires that the feature be maintained in major web servers. Which it will be. On a per-site basis, the developer needs to do nothing.

Still not getting it. Every site is hosted. The hosting company needs to spend money on HTTP/2, and be allowed to use it. The networks need to allow TCP through. All the steps down to the transport layer now require legacy maintenance.

Lots of things need to happen for HTTP/2 to 'stay alive'.

Your use of the future tense does not convince me.

The hosting company needs to spend basically nothing, because it's built into the software.

It's built into the software because enough sites will still be using it fifty years from now, even if it's a minority of traffic.

I seriously doubt you'll ever see TCP blocked.
