Bitcoin would be so much more if community and developers wouldn't be so stubborn on keeping protocol at certain version.

There would be no need for altcoins to exist, there would be no need for convulsed Lightning Network.
The price would be way over 100k today because it would actually be used instead of horded and people wishing for it to go up, praying more big investors would pump their bags, praying for more regulations instead of fighting the machine and become money that everyone needs.

Instead we have Digital Property with collapsing roof.
