you do what you can.

Substitute labour intensive alternatives. Its generally quite easy for recreation just go to an open mic night in the pub or a pwyf concert instead of all these streaming things. or take a walk in the park, or a hike in the hills instead of spending money on entertainment. Something like a game of football/soccer is pretty ultimate socialism entertainment - just don't pay to watch other people get your kicks for you.

Go out of your way to use public transport as much as possible even if it's slower or more inconvenient. This good practice in compromise to try social efficiency and sharing assets over individualistic self centredness - this is basically tragedy of commons/prisoners dilemma though so . . . ultimately your society will need some general trust for this to work - and it will break down often.

If you need stuff prefer patent expired or open source stuff, or just old second hand stuff. also get buy it for life stuff.
Personally i can have hours of fun with a discarded wood pallet and some very old hand tools.

Patent expired i.e. more open to competition/"free" market forces is like one step more socialised than the oligopolised stuff.
(That is where the free applies to the trades in the market and access to it, not to the people who want the 'freedom' to restrict trade and market entry.)

You can also try to share stuff with your friends and neighbors - that's pretty sociable.
At the end of the day though land and food is essential, so if that's not available socially, you're fucked.
Grow what you can and share it around i guess.
